Subject: [PATCH 0/4] media: Add devm-managed helper functions for media and V4L2 subsystems

This patch series introduces devm-managed versions of several commonly used
media and V4L2 initialization functions. These helpers simplify resource
management by leveraging the devres infrastructure, ensuring automatic
cleanup when the associated device is detached or the driver is unloaded.

Tested with IMX219 and OV2735 camera sensors on an i.MX8MP-based platform.

Tarang Raval (4):
  media: mc: Add devm_media_entity_pads_init() helper
  media: v4l: async: Add devm_v4l2_async_register_subdev_sensor() helper
  media: v4l2: subdev: Add devm_v4l2_subdev_init_finalize() helper
  media: v4l2-ctrls: Add devm_v4l2_ctrl_handler_init() helper
