Subject: [PATCH] drm/i915/huc: Simplify intel_huc_init_hw()
Date: Fri, 31 Mar 2017 11:57:09 +0000 [thread overview]
Message-ID: <20170331115709.181940-1-michal.wajdeczko@intel.com> (raw)
On last guc/huc cleanup series we've simplified guc init hw
function but missed the one for the huc. While here, change
its signature as we don't care about huc loading status.
