Subject: [patch] video: comparing unsigned with negative 0
Date: Wed, 07 Apr 2010 09:41:14 +0000 [thread overview]
Message-ID: <20100407094114.GH5157@bicker> (raw)
soc_mbus_bytes_per_line() returns -EINVAL on error but we store it in an
unsigned int so the test for less than zero doesn't work. I think it
always returns "small" positive values so we can just cast it to int
here.
