From: Sakari Ailus Date: Wed, 23 Aug 2023 09:03:42 +0000 (+0300) Subject: media: v4l2-mc: Make v4l2_pipeline_pm_{get,put} deprecated X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b97213a41140b87f48865ba594a1f4b5c5566631;p=linux.git media: v4l2-mc: Make v4l2_pipeline_pm_{get,put} deprecated 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.
