This patch (as1464) implements the recommended policy that most errors
during suspend or hibernation should not prevent the system from going
to sleep. In particular, failure to suspend a USB driver or a USB
device should not prevent the sleep from succeeding:
Failure to suspend a device won't matter, because the device will
automatically go into suspend mode when the USB bus stops carrying
packets. (This might be less true for USB-3.0 devices, but let's not
worry about them now.)
Failure of a driver to suspend might lead to trouble later on when the
system wakes up, but it isn't sufficient reason to prevent the system
from going to sleep.
