From 01a9ca0ba87176432f0b91fd9adbfa66e33253ed Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Fri, 31 Mar 2017 11:57:09 +0000 Subject: [PATCH] drm/i915/huc: Simplify intel_huc_init_hw() 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.
