| |
return type of wait_for_completion_timeout is unsigned long not int. A appropriately named variable of type unsigned long is added and the assignments fixed up.
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> ---
v2: added config used for compile testing.
Patch was only compile tested with x86_64_defconfig + CONFIG_USB=m, CONFIG_MEDIA_SUPPORT=m, CONFIG_MEDIA_ANALOG_TV_SUPPORT=y CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y, (implies VIDEO_V4L2=m) CONFIG_MEDIA_RADIO_SUPPORT=y, CONFIG_RADIO_SI470X=y CONFIG_USB_SI470X=m
Patch is against 3.19.0 (localversion-next is -next-20150211)
