From f78ae63f28c3f7de06360c553711fb07abd69734 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 19 Jan 2015 13:50:52 +0200 Subject: [PATCH] drm/i915: Rename 'reg' to 'clk_reg' to unconfuse it from the other 'reg' MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On VLV/CHV the rc6 residency calculations read a second register to determine the actual units used for the residency value. The variable name 'reg' where that register value is stored shadows the function argument 'reg'. That can easily leave the reader utterly confused, so rename the internal variable to 'clk_reg'.
