[PATCH 05/18] Input: retu-pwrbutton - simplify function return logic

[Javier Martinez Canillas]

The invoked function already returns zero on success or a negative
errno code so there is no need to open code the logic in the caller.

This also fixes the following make coccicheck warning:

drivers/input/misc/retu-pwrbutton.c:72:1-6: WARNING: end returns can be simplified
