Subject: [PATCH v2 3/4] media: cedrus: Wrap PHYS_PFN_OFFSET with ifdef and add dedicated comment
Date: Sun, 9 Sep 2018 21:10:14 +0200 [thread overview]
Message-ID: <20180909191015.20902-4-contact@paulk.fr> (raw)
In-Reply-To: <20180909191015.20902-1-contact@paulk.fr>
Since PHYS_PFN_OFFSET is not defined for all architectures, it is
requried to wrap it with ifdef so that it can be built on all
architectures.
