From 3a1e3c483584762c794fb21795ed02982c8cdcf7 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Wed, 11 Dec 2019 12:45:48 +0000 Subject: [PATCH] drm/i915/uc: Drop explicit gt param in some uc_fw functions There is no need to pass explicit gt since we already have a trick to get parent gt from uc_fw, we only need to use it.
