Subject: [PATCH] drm/i915: Clean up LVDS register handling harder
Date: Thu, 5 Nov 2015 09:30:50 +0100	[thread overview]
Message-ID: <20151107141244.AB7616E242@gabe.freedesktop.org> (raw)

Minor fixup to d0669d007542 ("drm/i915: Clean up LVDS register
handling") which intended to read lvds_reg just once at the
beginning of intel_lvds_init() and use that throughout the rest
of the function but accidentally missed one register readout.
