[PATCH v2 03/11] media: i2c: ov5645: Enable runtime PM after v4l2_async_register_subdev()

From: Prabhakar
Date: Tue Sep 10 2024 - 13:07:15 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

To simplify the probe error path, enable runtime PM after the
v4l2_async_register_subdev() call.

This change ensures that runtime PM is only enabled once the subdevice
registration is successful, avoiding unnecessary cleanup in the error
path.
