From 4319382e9b1bbcf39aa6bfc89db7a431776b693a Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Mon, 25 Mar 2019 14:49:37 -0700 Subject: [PATCH] drm/i915: switch intel_uncore_forcewake_for_reg to intel_uncore The intel_uncore structure is the owner of FW, so subclass the function to it. While at it, use a local uncore var and switch to the new read/write functions where it makes sense.
