return type of wait_for_completion_timeout is unsigned long not int, this patch assigns the return value of wait_for_completion_timeout to an appropriately typed and named variable.
Signed-off-by: Nicholas Mc Guire hofrat@osadl.org
This was compile tested with qcom_defconfig + CONFIG_DRM=m (implies CONFIG_DRM_MSM=m)
Patch is against 4.0-rc7 (localversion-next is -next-20150410)

Given that time_left is unsigned now, why bother with the "< 0"?
