kernel build failed in ubuntu 20.04 with kernel 5.10.4 #227

Hello,

I've pulled latest code from repository. I've disabled ov9650 in menuconfig and I can not find anything remotely similar to via-camera in 5.10.4 .config file. any suggestions?

my kernel build fails with following errors:

MODPOST /home/ali/utv-scripts/build/media_build/v4l/Module.symvers ERROR: modpost: "viafb_release_dma" [/home/ali/utv-scripts/build/media_build/v4l/via-camera.ko] undefined!

I'm documenting the result I've found. If (Device Drivers > Multimedia support > Media drivers > V4L platform devices) and under it (VIAFB camera controller support) is not selected, then CONFIG_VIDEO_VIA_CAMERA is not even exist in kernel config file and could not be searched in make menuconfig. That was the reason I was unable to find anything about via-camera module. After enabling said options and recompiling kernel modules, via-camera module built, and then TBS drivers compiled successfully.
