Public bug reported:
On my ASUS T100TAM (old Bay Trail 2-in-1 laptop) the webcam is the last
non-working piece of hardware. The following dmesg snippet seems to
suggest that the kernel needs a special config flag:
[ 25.478178] atomisp_gmin_platform: module is from the staging directory, the
quality is unknown, you have been warned.
[ 25.478274] atomisp_gmin_platform: module verification failed: signature

Is this something that could be considered for the next kernels? Can I
preview test it somehow? Keep in mind that this laptop is pretty slow...
