From d5ce4164899330e616c4ef067412ba2a4833f6d8 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Wed, 4 Nov 2015 17:10:45 -0200 Subject: [PATCH] drm/i915: rename intel_fbc_nuke to intel_fbc_recompress Although the term "nuke" is part of the FBC spec, it's not very intuitive, so let's rename it to make it easier for people that are not familiar with the spec.
