usb: phy: twl6030: add IRQ checks
[ Upstream commit 0881e22c06e66af0b64773c91c8868ead3d01aa1 ]
The driver neglects to check the result of platform_get_irq()'s calls and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing them both to fail with -EINVAL, overriding
an original error code. Stop calling request_threaded_irq() with the
invalid IRQ #s.
Fixes: c33fad0c3748 ("usb: otg: Adding twl6030-usb transceiver driver for OMAP4430")
