Subject: [PATCH 04/12] drm/i915: Add i9xx_lut_8()
Date: Thu,  7 Nov 2019 17:17:17 +0200	[thread overview]
Message-ID: <20191107151725.10507-5-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20191107151725.10507-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We have a nice little helper to compute a single LUT entry
for everything except the 8bpc legacy gamma mode. Let's
complete the set.
