HID: picoLCD: Deletion of unnecessary checks before three function calls

2015-06-29T12:51:12+00:00

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.

HID: use hid_hw_request() instead of direct call to usbhid

2013-02-25T12:26:41+00:00

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.

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).
