Subject: [PATCH v9 12/24] v4l: async: Register sub-devices before calling bound callback
Date: Fri, 8 Sep 2017 16:18:10 +0300 [thread overview]
Message-ID: <20170908131822.31020-8-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20170908131235.30294-1-sakari.ailus@linux.intel.com>
Register the sub-device before calling the notifier's bound callback.
Doing this the other way around is problematic as the struct v4l2_device
has not assigned for the sub-device yet and may be required by the bound
callback.
