From: Ville Syrjälä Date: Tue, 25 Jun 2013 16:21:01 +0000 (+0300) Subject: drm/i915: Clean up VLV rps code a bit X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73008b989faf4200907a858f9b902ee29d6edbea;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: Clean up VLV rps code a bit Always print both the MHz value and raw register value for rps stuff. Also kill a somewhat pointless local 'rpe' variable and just use dev_priv->rps.rpe_delay. While at it clean up the caps in "GPU" and "Punit" debug messages.
