From c2079f3e220e2f0b551715ee748a0cc936a4a7f6 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Mon, 19 Sep 2022 13:07:30 +0300 Subject: media: v4l: subdev: Document s_power() callback is deprecated Runtime PM has been around for a decade or more, there's hardly a need to use the V4L2 specific s_power() callback in drivers anymore. Document this in s_power() callback documentation as well.
