Subject: [PATCH] drm/i915/psr: Fix register name mess up.
Date: Tue, 19 Dec 2017 20:35:20 -0800 [thread overview]
Message-ID: <20171220043520.2599-1-dhinakaran.pandiyan@intel.com> (raw)
Commit 77affa31722b ("drm/i915/psr: Fix compiler warnings for
hsw_psr_disable()") swapped status and control registers while fixing
indentation. The _ctl at the end of the status register name must have to
led to this.
