[RFC PATCH 03/12] media: i2c: ov5645: Enable runtime PM after v4l2_async_register_subdev()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
