Subject[PATCH] media: fix !CONFIG_MEDIA_CONTROLLER compile error for v4l_change_media_source()
Date
This error is a result of not defining v4l_change_media_source() stub
in include/media/v4l2-mc.h for !CONFIG_MEDIA_CONTROLLER case.

Fix the following compile error:

url: https://github.com/0day-ci/linux/commits/Shuah-Khan/media-add-change_source-handler-support/20160310-131140
base: git://linuxtv.org/media_tree.git master
config: x86_64-rhel (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All errors (new ones prefixed by >>):

drivers/media/usb/au0828/au0828-video.c: In function 'vidioc_s_input':
>> drivers/media/usb/au0828/au0828-video.c:1474:2: error: implicit declaration of function 'v4l_change_media_source' [-Werror=implicit-function-declaration]
return v4l_change_media_source(vfd);
^
cc1: some warnings being treated as errors
