[PATCH 0/4] mfd: qnap-mcu: Some fixes / improvements

[Heiko Stuebner <heiko@sntech.de>]

While digging through the mcu functions, I came across some deficits I
introduced with the initial driver submission, so trying to make that
a bit nicer with this series.


I struggled a bit with the ordering of qnap_mcu_write error-check
and conversion to guard(mutex). Converting to guard before the
error check would need dropping the ret variable, just to re-add it
one patch later - to not cause unused variable warning.

Additionally the error handling could be considered a fix, so makes
sense to have in front.


Heiko Stuebner (4):
  mfd: qnap-mcu: include linux/types.h in qnap-mcu.h shared header
  mfd: qnap-mcu: handle errors returned from qnap_mcu_write
  mfd: qnap-mcu: convert to guard(mutex) in qnap_mcu_exec
  mfd: qnap-mcu: improve structure in qnap_mcu_exec
