Subject: [PATCH v5 1/2] media: vimc: move the dev field of each entity to vimc_ent_dev
Date: Thu, 24 Oct 2019 16:15:53 +0200 [thread overview]
Message-ID: <20191024141554.15248-2-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20191024141554.15248-1-dafna.hirschfeld@collabora.com>
Since the 'struct device *dev' field exists in each of the
entity structs, it can be moved to the common struct vimc_ent_devevice.
It is then used to replace 'pr_err' with 'dev_err' in the streamer
code.
