Subject: [PATCH] [media] exynos4-is: fix error handling of irq_of_parse_and_map
Date: Fri, 14 Nov 2014 14:09:50 -0800 [thread overview]
Message-ID: <20141114220950.GA34576@dtor-ws> (raw)
Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.
Signed-off-by: Dmitry Torokhov <dtor@chromium.org>
