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()'
