commit: 62c6b4c9e3c8e30ba4ad6c85732f00a26c5e4394 [265/273] media: vivid: move the devnode creation logic to a separate function
config: i386-randconfig-r011-20200907 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-15) 9.3.0
reproduce (this is a W=1 build):
git checkout 62c6b4c9e3c8e30ba4ad6c85732f00a26c5e4394
# save the attached .config to linux build tree
make W=1 ARCH=i386

Note: the linuxtv-media/master HEAD d034731bb4b4f2bf5f378231a6d99e59c2cb59f6 builds fine.
It only hurts bisectibility.
