[PATCH 1/3] drm/msm: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

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 at 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)
