From 7b44e4de72dcd5a5769ad19c5cc2cc2b28c0a778 Mon Sep 17 00:00:00 2001 From: Maxime Ripard <maxime@cerno.tech> Date: Mon, 11 Jul 2022 19:39:06 +0200 Subject: [PATCH] drm/vc4: dsi: Switch to devm_pm_runtime_enable devm_pm_runtime_enable() simplifies the driver a bit since it will call pm_runtime_disable() automatically through a device-managed action.
