Subject: wifi: wfx: Remove some dead code
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=015bf4df8ea67080668ac8314e692076dea1ce6d;p=linux.git

wifi: wfx: Remove some dead code

wait_for_completion_timeout() can not return a <0 value.
So simplify the logic and remove dead code.

-ERESTARTSYS can not be returned by do_wait_for_common() for tasks with
TASK_UNINTERRUPTIBLE, which is the case for wait_for_completion_timeout()
