wait_for_completion_timeout() returns unsigned long not int. This assigns
the return value to an appropriately typed variable (also helps keep 
static code checkers happy).

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

Patch was only compile tested with x86_64_defconfig + CONFIG_MEDIA_SUPPORT=m
CONFIG_MEDIA_CAMERA_SUPPORT=y, CONFIG_V4L_PLATFORM_DRIVERS=y,
CONFIG_MEDIA_RADIO_SUPPORT=y, RADIO_ADAPTER=y, CONFIG_RADIO_WL1273=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
