Subject: media: v4l2-mc: Make v4l2_pipeline_pm_{get,put} deprecated
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Wed Aug 23 12:03:42 2023 +0300
The v4l2_pipeline_pm_get() and v4l2_pipeline_pm_put() functions were
needed to control sub-devices' power states before runtime PM. These
functions should no longer be used, and instead sub-device drivers should
use runtime PM.
