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) drivers/gpu/drm/msm/edp/edp_ctrl.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-)
