From: Chris Wilson Date: Fri, 1 Jul 2016 16:23:13 +0000 (+0100) Subject: drm/i915: Make queueing the hangcheck work inline X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26a02b8fc35ff2c393505bccd9f046e8d50c1708;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Make queueing the hangcheck work inline Since the function is a small wrapper around schedule_delayed_work(), move it inline to remove the function call overhead for the principle caller.
