From 2cb2cb5ff41abd92d6a7bfb1459b25974fa6d509 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 14 Jan 2019 14:21:21 +0000 Subject: [PATCH] drm/i915/panel: Track temporary rpm wakeref Keep track of the temporary rpm wakeref used for panel backlight access, so that we can cancel it immediately upon release and so more clearly identify leaks.
