Hi, thanks for recreating and looking into this. What I've done is
disabled powertop auto tunables as a system service and then looked at
that value. With powertop not running it is indeed set to ON for both
kernels. With powertop running it gets set to AUTO. So I think as was
alluded to earlier po

"System Clock" seems to be handled in another patch.

uwbd_start() calls kthread_run() and checks that the return value is
not NULL. But the return value is not NULL in case kthread_run() fails,
it takes the form of ERR_PTR(-EINTR).
Use IS_ERR() instead.

This uncovers another issue,
uwbd_start() calls kthread_run() and checks that the return value is
not NULL. But the return value is not NULL in case kthread_run() fails,
it takes the form of ERR_PTR(-EINTR).
Use IS_ERR() instead.
Also add a check to uwbd_stop().

I'm a little unclear about USB Video Class (UVC). In order to use the
camera, does it need to have a Video4Linux driver that "talks" to a
UVC class or it is possible to have a camera that doesn't have a
Video4Linux driver and interfaces to a UVC directly?
