From: Chris Wilson Date: Sun, 12 Feb 2017 17:19:59 +0000 (+0000) Subject: drm/i915: Always call i915_gem_reset_finish() following i915_gem_reset_prepare() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b2e5ea0b7061be3ffdcd85918c2f428edace4ba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Always call i915_gem_reset_finish() following i915_gem_reset_prepare() As i915_gem_reset_finish() undoes the steps from i915_gem_reset_prepare() to leave the system in a fully-working state, e.g. to be able to free the breadcrumb signal threads, make sure that we always call it even on the error path.
