Subject: [PATCH v2 07/12] media: ov2740: Enable runtime PM before registering the async subdev
Date: Mon, 18 Sep 2023 15:51:33 +0300 [thread overview]
Message-ID: <20230918125138.90002-8-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20230918125138.90002-1-sakari.ailus@linux.intel.com>
Enable runtime PM before registering the async subdev as the driver UAPI
may become accessible immediately after the registration. Runtime PM needs
to be enabled by that time.
