Regression: active uvcvideo breaks over suspend

[Alan Jenkins]

I found this in v2.6.30-rc2.  I haven't tested beyond that.  I'm sure it 
didn't happen in 2.6.29.

If I run "xawtv" and then suspend, it stops working on resume; the xawtv 
display goes black and the camera LED stays off.  When I close xawtv, 
the LED blinks on then off again.  If I then try to run xawtv again, it 
works fine.

In dmesg (after resume) I see

[  562.884298] usb 1-8: type resume
[  562.990014] usb 1-8: reset high speed USB device using ehci_hcd and 
address 3

Thanks in advance
