Subject: [PATCH v2 1/5] media: vimc: initialize vim entity pointers to NULL
Date: Thu, 3 Oct 2019 12:44:05 +0200 [thread overview]
Message-ID: <20191003104409.15756-2-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20191003104409.15756-1-dafna.hirschfeld@collabora.com>
since NULL value for vimc entity pointer indicates
that entity creation failed and this is tested, the
pointers should be initialized to NULL.
