Markus Elfring 4b8a826208 HID: picoLCD: Deletion of unnecessary checks before three function calls
The functions backlight_device_unregister(), lcd_device_unregister() and
rc_unregister_device() test whether their argument is NULL and then
return immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Benjamin Tissoires d881427253 HID: use hid_hw_request() instead of direct call to usbhid
This allows the hid drivers to be independent from the transport layer.

The patch was constructed by replacing all occurences of
usbhid_submit_report() by its hid_hw_request() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.

Finally, few drivers still depends on USB_HID. Many of them
are requiring the io wait callback. They are found in the next patch.

Bruno Prémont fabdbf2fd2 HID: picoLCD: split driver code
In order to make code maintenance easier, split the vairous
functions into individial files (this removes a bunch of #ifdefs).
