Subject: drm/i915: Sanitize i915_gem_load() init and clean-up
X-Git-Tag: v4.6-rc1~12^2~28^2~96
X-Git-Url: http://git.cascardo.info/?a=commitdiff_plain;h=d64aa096a4fb0f438563ad8126123766c2190aa8;p=cascardo%2Flinux.git

drm/i915: Sanitize i915_gem_load() init and clean-up

Factor out common clean-up code for the GEM load time init function.
Also rename i915_gem_load() to i915_gem_load_init() to have a better
match with its new clean-up function.

No functional change.
