Subject: [v5][PATCH 08/11] drm/i915: Extract bdw_read_luts()
Date: Sat,  4 May 2019 22:41:37 +0530	[thread overview]
Message-ID: <1556989900-21972-9-git-send-email-swati2.sharma@intel.com> (raw)
In-Reply-To: <1556989900-21972-1-git-send-email-swati2.sharma@intel.com>

In this patch, gamma and degamma hw blobs are created for BDW.

v4: -No need to initialize *blob [Jani]
    -Removed right shifts [Jani]
    -Dropped dev local var [Jani]
v5: -Returned blob instead of assigning it internally within the
     function [Ville]
    -Renamed bdw_get_color_config() to bdw_read_luts() [Ville]
    -Enabled degamma lut validation [Ville]
