[PATCH 0/4] HID: alps: Fix some bugs and improve code around 't4_read_write_register()'

[Christophe JAILLET]

All is said in the subject and below.

These patches are untested. Especially, patch 1 slightly changes the behavior
of 't4_read_write_register()'.
This looks logical to me, but please, review it carefully.

Christophe JAILLET (4):
  HID: alps: Report an error if we receive invalid data in
    't4_read_write_register()'
  HID: alps: Save a memory allocation in 't4_read_write_register()' when
    writing data
  HID: alps: Check errors returned by 't4_read_write_register()'
  HID: alps: Fix some style in 't4_read_write_register()'
