If demod (and tuner) is powered off by bridge (.power_ctrl) that's not

in sleep case. But that does not sounds good solution...
Michael Krufky actually put together some patches to allow the bridge
to intercept frontend calls, which would allow for things like power
management. I don't know if they've been merged yet.
OK, lets see.
I wonder why v4l-dvb -framework even allows IOCTLs when device is
powered off. This sounds like wrong functionality from my sight. Why not
to power on device before all IOCTL request. Some IOCTLs like
SET_FRONTEND will of course power on device but most not.
