This is a backport of commit 5f677f1d45.
Some of the functionality had to be removed, but it should still fix
the webcam problem.
This patch (as1363b) changes the way USB remote wakeup is handled
during system sleeps. It won't be enabled unless an interface driver
specifically needs it. Also, it won't be enabled during the FREEZE or
QUIESCE phases of hibernation, when the system doesn't respond to
wakeup events anyway.
This will fix problems people have reported with certain USB webcams
that generate wakeup requests when they shouldn't, and as a result
cause system suspends to fail. See
