From 26a02b8fc35ff2c393505bccd9f046e8d50c1708 Mon Sep 17 00:00:00 2001 From: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri, 1 Jul 2016 17:23:13 +0100 Subject: [PATCH] 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.
