Subject: [PATCH 07/18] Input: cap11xx - simplify function return logic

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/keyboard/cap11xx.c:475:1-6: WARNING: end returns can be simplified
