Subject: [PATCH 1/4] media: staging: rkisp1: change function to return void instead of int
Date: Fri,  7 Feb 2020 09:59:48 +0100
Message-ID: <20200207085951.5226-2-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20200207085951.5226-1-dafna.hirschfeld@collabora.com>

There are functions that return int but actually return always 0.
Change them to return void and then there is no need to check
for error return value.
