commit 20934c0de13b49a072fb1e0ca79fe0fe0e40eae5 upstream.
The PSZ-HA* family of USB disk drives from Sony can't handle the
REPORT OPCODES command when using the UAS protocol. This patch adds
an appropriate quirks entry.

commit 1d4169834628d18b2392a2da92b7fbf5e8e2ce89 upstream.
If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ohci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.

commit 9aa37788e7ebb3f489fb4b71ce07adadd444264a upstream.
This device does not support UAS properly and a similar entry already
exists in drivers/usb/storage/unusual_uas.h. Without this patch,
storage_probe() defers the handling of this device to UAS, which cannot
handle it either.

commit 9a469bc9f32dd33c7aac5744669d21a023a719cd upstream.
PNY Pro Elite USB 3.1 Gen 2 device (SSD) doesn't respond to ATA_12
pass-through command (i.e. it just hangs). If it doesn't support this
command, it should respond properly to the host. Let's just add a quirk
to be able to move forward with other operations.

GFP_KERNEL as a memory-allocation flag to usb_submit_urb() at a time
when its state is TASK_INTERRUPTIBLE, not TASK_RUNNING:

commit 904df64a5f4d5ebd670801d869ca0a6d6a6e8df6 upstream.
Sometimes re-plugging a USB device during system sleep renders the device
useless:
[ 173.418345] xhci_hcd 0000:00:14.0: Get port status 2-4 read: 0x14203e2, return 0x10262
...
[ 176.496485] usb 2-4: Waited 2000ms for CONNECT
[ 176.496781] usb usb2-port4: status 0000.0262 after resume, -19
[ 176.497103] usb 2-4: can't resume, status -19
[ 176.497438] usb usb2-port4: logical disconnect
Because PLS equals to XDEV_RESUME, xHCI driver reports U3 to usbcore,
despite of CAS bit is flagged.
So proritize CAS over XDEV_RESUME to let usbcore handle warm-reset for
the port.

commit 531412492ce93ea29b9ca3b4eb5e3ed771f851dd upstream.
lvs_rh_probe() can return some nonnegative value from usb_control_msg()
when it is less than "USB_DT_HUB_NONVAR_SIZE + 2" that is considered as
a failure. Make lvs_rh_probe() return -EINVAL in this case.

[ Upstream commit 2b53a19284f537168fb506f2f40d7fda40a01162 ]
The char buffer buf, receives data directly from user space,
so its content might be negative and its elements are left
shifted to form an unsigned integer.
Since left shifting a negative value is undefined behavior, thus
change the char to u8 to elimintate this UB.

[ Upstream commit 33a06f1300a79cfd461cea0268f05e969d4f34ec ]
When gadget registration fails, one should not call usb_del_gadget_udc().
Ensure this by setting gadget->udc to NULL. Also in case of a failure
there is no need to disable low-level hardware, so return immiedetly
instead of jumping to error_init label.
This fixes the following kernel NULL ptr dereference on gadget failure
(can be easily triggered with g_mass_storage without any module
parameters):
dwc2 12480000.hsotg: dwc2_check_params: Invalid parameter besl=1

While fixing this also fix the double call to dwc2_lowlevel_hw_disable()
if dr_mode is set to USB_DR_MODE_PERIPHERAL. In such case low-level
hardware is already disabled before calling usb_add_gadget_udc(). That
function correctly preserves low-level hardware state, there is no need
for the second unconditional dwc2_lowlevel_hw_disable() call.

[ Upstream commit a95bdfd22076497288868c028619bc5995f5cc7f ]
Multiple connects/disconnects can cause a crash on the second
disconnect. The driver had a problem where it would try to send
endpoint commands after it was disconnected which is not allowed
by the hardware. The fix is to only allow the endpoint commands
when the endpoint is connected. This will also fix issues that
showed up when using configfs to create gadgets.

commit 5d0136f8e79f8287e6a36780601f0ce797cf11c2 upstream.
Add PID for CH340 that's found on some ESP8266 dev boards made by
LilyGO. The specific device that contains such serial converter can be
seen here: https://github.com/LilyGO/LILYGO-T-OI.
Apparently, it's a regular CH340, but I've confirmed with others that
also bought this board that the PID found on this device (0x7522)
differs from other devices with the "same" converter (0x7523).
Simply adding its PID to the driver and rebuilding it made it work
as expected.

commit 5c45d04c5081c1830d674f4d22d4400ea2083afe upstream.
This is a UPB (Universal Powerline Bus) PIM (Powerline Interface Module)
which allows for controlling multiple UPB compatible devices from Linux
using the standard serial interface.
Based on vendor application source code there are two different models
of USB based PIM devices in addition to a number of RS232 based PIM's.
The vendor UPB application source contains the following USB ID's:
#define USB_PCS_VENDOR_ID 0x04b4
#define USB_PCS_PIM_PRODUCT_ID 0x5500
#define USB_SAI_VENDOR_ID 0x17dd
#define USB_SAI_PIM_PRODUCT_ID 0x5500
The first set of ID's correspond to the PIM variant sold by Powerline
Control Systems while the second corresponds to the Simply Automated
Incorporated PIM. As the product ID for both of these match the default
cypress HID->COM RS232 product ID it assumed that they both use an
internal variant of this HID->COM RS232 converter hardware. However
as the vendor ID for the Simply Automated variant is different we need
to also add it to the cypress_M8 driver so that it is properly
detected.

If wakeup event occurred by extcon event, it needs to call
ci_irq again since the first ci_irq calling at extcon notifier
only wakes up controller, but do noop for event handling,
it causes the extcon use case can't work well from low power mode.

clang static analysis flags this error
c67x00-sched.c:489:55: warning: Use of memory after it is freed [unix.Malloc]
usb_hcd_giveback_urb(c67x00_hcd_to_hcd(c67x00), urb, urbp->status);
^~~~~~~~~~~~
Problem happens in this block of code
c67x00_release_urb(c67x00, urb);
usb_hcd_unlink_urb_from_ep(c67x00_hcd_to_hcd(c67x00), urb);
spin_unlock(&c67x00->lock);
usb_hcd_giveback_urb(c67x00_hcd_to_hcd(c67x00), urb, urbp->status);
In the call to c67x00_release_urb has this freeing of urbp
urbp = urb->hcpriv;
urb->hcpriv = NULL;
list_del(&urbp->hep_node);
kfree(urbp);
And so urbp is freed before usb_hcd_giveback_urb uses it as its 3rd
parameter.
Since all is required is the status, pass the status directly as is
done in c64x00_urb_dequeue

commit e901b9873876ca30a09253731bd3a6b00c44b5b0 upstream.
This patch adds a new helper function to perform a sanity check of the
given URB to see whether it contains a valid endpoint. It's a light-
weight version of what usb_submit_urb() does, but without the kernel
warning followed by the stack trace, just returns an error code.
Especially for a driver that doesn't parse the descriptor but fills
the URB with the fixed endpoint (e.g. some quirks for non-compliant
devices), this kind of check is preferable at the probe phase before
actually submitting the urb.

If this is in "transceiver" mode the the ->qwork isn't required and is
a NULL pointer. This can lead to a NULL dereference when we call
destroy_workqueue(udc->qwork).

[ Upstream commit b3d71abd135e6919ca0b6cab463738472653ddfb ]
USB2 devices with LPM enabled may interrupt the system suspend:

[ 932.591405] PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16
[ 932.591414] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -16
[ 932.591418] PM: Device 0000:00:14.0 failed to suspend async: error -16
During system suspend, USB core will let HC suspends the device if it
doesn't have remote wakeup enabled and doesn't have any children.
However, from the log above we can see that the usb 1-7 doesn't get bus
suspended due to not in U0. After a while the port finished U2 -> U0
transition, interrupts the suspend process.
The observation is that after disabling LPM, port doesn't transit to U0
immediately and can linger in U2. xHCI spec 4.23.5.2 states that the
maximum exit latency for USB2 LPM should be BESL + 10us. The BESL for
the affected device is advertised as 400us, which is still not enough
based on my testing result.
So let's use the maximum permitted latency, 10000, to poll for U0
status to solve the issue.

commit 03894573f2913181ee5aae0089f333b2131f2d4b upstream.
USB_DEVICE(0x0424, 0x274e) can send data before cdc_acm is ready,
causing garbage chars on the TTY causing stray input to the shell
and/or login prompt.

commit a73d9d9cfc3cfceabd91fb0b0c13e4062b6dbcd7 upstream.
Unable to complete the enumeration of a USB TV Tuner device.
Per XHCI spec (4.6.5), the EP state field of the input context shall
be cleared for a set address command. In the special case of an FS
device that has "MaxPacketSize0 = 8", the Linux XHCI driver does
not do this before evaluating the context. With an XHCI controller
that checks the EP state field for parameter context error this
causes a problem in cases such as the device getting reset again
after enumeration.
When that field is cleared, the problem does not occur.
This was found and fixed by Sasi Kumar.

commit dceea67058fe22075db3aed62d5cb62092be5053 upstream.
EP_STATE_MASK should be 0x7 instead of 0xf
xhci spec 6.2.3 shows that the EP state field in the endpoint context data
structure consist of bits [2:0].
The old value included a bit from the next field which fortunately is a
RsvdZ region. So hopefully this hasn't caused too much harm

commit 44ed240d62736ad29943ec01e41e194b96f7c5e9 upstream.
If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ehci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.

commit 1ddcb71a3edf0e1682b6e056158e4c4b00325f66 upstream.
A Synopsys USB2.0 core used in Huawei Kunpeng920 SoC has a bug which
might cause the host controller not issuing ping.
Bug description:
After indicating an Interrupt on Async Advance, the software uses the
doorbell mechanism to delete the Next Link queue head of the last
executed queue head. At this time, the host controller still references
the removed queue head(the queue head is NULL). NULL reference causes
the host controller to lose the USB device.
Solution:
After deleting the Next Link queue head, when has_synopsys_hc_bug set
to 1，the software can write one of the valid queue head addresses to
the ASYNCLISTADDR register to allow the host controller to get
the valid queue head. in order to solve that problem, this patch set
the flag for Huawei Kunpeng920
There are detailed instructions and solutions in this patch:
