Subject: [PATCH 10/11] drm: stm: remove dead code and pointless local lut storage
Date: Tue, 20 Jun 2017 21:25:34 +0200 [thread overview]
Message-ID: <1497986735-14418-11-git-send-email-peda@axentia.se> (raw)
In-Reply-To: <1497986735-14418-1-git-send-email-peda@axentia.se>
The redundant fb helper .load_lut is no longer used, and can not
work right without also providing the fb helpers .gamma_set and
.gamma_get thus rendering the code in this driver suspect.
Just remove the dead code.
