However when generic HID code has been converted to bus and individual quirks separated out to individual drivers on the bus, the copyright has been blindly transfered into all the tiny drivers, which actually don't contain any of Pauls' copyrighted code. Remove the copyright from those sub-drivers. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Paul Walmsley <paul@pwsan.com>
| * | | | HID: Remove "default m" from HID_LOGITECH_DJJosh Triplett2012-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HID_LOGITECH_DJ uses "default m", which enables it in default kernel builds. Since this module just enables extra, non-critical functionality for one particular piece of hardware (specifically, differentiating multiple wireless keyboards and mice as separate input devices rather than treating them as one device), and the hardware works just fine with the default USB HID support, drop the "default m".

| * | | | | HID: Bump maximum global item tag report size to 128 bytesMarek Vasut2012-08-15

Linux checks if this is 96 as of now, see [1]. This causes Linux to refuse to communicate with this device, making it impossible to use the recovery mode. This is not a standard HID device per se, but rather a software emulation implemented within the BootROM code and realized through USB OTG-capable port switched to device mode present on the device. Previous attempt to discuss this issue dates back to 2011, see [2]. There has been not much response. Also noteworthy is the [3], where there seems to be a pointing device that has issue similar to this one. The tool making use of the USB recovery mode is available at [4].

This way fb_info may cleanly outlive struct picolcd_data for as long as needed for its last user to drop his reference. Access to struct picolcd_data is now protected with struct picolcd_fb_data's lock and tile update reports are only generated while picolcd_fbdata->picolcd is not NULL and is not marked as failed (which indicates unplug in progress).

It is however possible to overpower the FFB motors quite easily which leads to the X axis value exceeding the expected limit. This confuses games which dynamically adjust calibration using the highest/lowest min and max values reported by the wheel. Joydev device driver also doesn't take in account any changes in an axis range after the joystick device is created. This patch recalculates received ABS_X axis value so it is always in <0; 16383> range where 0 is the left limit and 16383 the right limit. Logitech driver for Windows does the same thing. As for any concerns about possible loss of precision, I compared a large set of raw/adjusted values generated by "mult_frac" to values returned by the Windows driver and I got a 100% match. Other Logitech wheels will probably need a similar fix, but I currently lack the information needed to write one.

After that commit, hid-core discards any incoming packet that arrives while hid driver's probe function is being executed. This broke the enumeration process of hid-logitech-dj, that must receive control packets in-band with the mouse and keyboard packets. Discarding mouse or keyboard data at the very begining is usually fine, but it is not the case for control packets. This patch forces a re-enumeration of the paired devices when a packet arrives that comes from an unknown device. Based on a patch originally written by Benjamin Tissoires.
