Input: pxrc - flatten probe code

2018-07-25T19:04:19Z

Instead of splitting probe code into separate USB and input setup, flatten it. This allows for easier inspection of order of set up steps, since the probe code is reasonably small. Move input-related initialization (phys) from USB block to input block. Reviewed-by: Marcus Folkesson Tested-by: Marcus Folkesson Signed-off-by: Dmitry Torokhov

Input: pxrc - do not store unneeded data in driver structure

2018-07-25T19:04:18Z

There is no need to store data buffer size, pointer to the buffer, or endpoint address in pxrc structure, as they are either only needed during setup, or are available from elsewhere. Reviewed-by: Marcus Folkesson Tested-by: Marcus Folkesson Signed-off-by: Dmitry Torokhov

Input: pxrc - move module device table closer to where it is used

2018-07-25T19:04:16Z

There is no need to have the device table first in the file. Reviewed-by: Marcus Folkesson Tested-by: Marcus Folkesson Signed-off-by: Dmitry Torokhov

Input: pxrc - fix freeing URB on device teardown

2018-07-25T19:04:15Z

URB is the only resource that is not managed, and thus is destroyed too early, before we unregister input device and stop URB in pxrc_close(). To fix it let's install custom devm handler to free the URB at the right time in devm unwind sequence. Reviewed-by: Marcus Folkesson Tested-by: Marcus Folkesson Signed-off-by: Dmitry Torokhov

Input: pxrc - do not store USB device in private struct

2018-07-25T19:04:13Z

The USB device is only needed during setup, so put it back after initialization and do not store it in our private struct. Also, the USB device is a parent of USB interface so our driver model rules ensure that USB device should not disappear while interface device is still there; there is no need to take reference to the USB device.
