Subject: OMAPDSS: DISPC: Fix the usage of wait_for_completion_timeout
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=864fa7f46162a32c7c18da0c15d04777aa34ac02;p=linux-beck.git

OMAPDSS: DISPC: Fix the usage of wait_for_completion_timeout

The return value of wait_for_completion_timeout() is always
>= 0 with unsigned int type.

So the condition "ret < 0" or "ret >= 0" is pointless.
