Andi, the problem here is, that v4l has only open in fops which in turn changes
fops to the driver's one, so this would mean change all the drivers in v4l...
I second the converting to unlocked_ioctl and compat_ioctl in longer term (for
new drivers as a merging rule), but wouldn't be feasible to add them to compat
ioctl for now?
