Subject: Input: twl6040-vibra - ignore return value of schedule_work
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5f7fb6f1e514e0ed47aee97752d6ae10491b4841;p=linux-beck.git

Input: twl6040-vibra - ignore return value of schedule_work

Returning ret is wrong. And checking for an error as well. User space
may call multiple times until the work is really scheduled.

twl4030-vibra.c also ignores the return value.
