generate "change" uevent for loop device
Recent udev versions probe loop devices for filesystems meaning that
the /dev/disk hierarchy may contain useful entries such as
$ ls -l /dev/disk/by-label/Fedora-12-x86_64-Live
lrwxrwxrwx 1 root root 11 Mar 11 13:41 /dev/disk/by-label/Fedora-12-x86_64-Live -> ../../loop0
Unfortunately, no "change" uevent is generated when the loop device is
detached so the symlink persists. Additionally, no "change" uevent is
guaranteed to be generated when attaching an fd or changing capacity.
For example, user space could open the loop device O_RDONLY (in fact,
recent util-linux-ng does this) so udev's OPTIONS+="watch" machinery may
not trigger the "change" uevent.
This patch ensures that the "change" uevent is generated in all of
these cases. As a result, the /dev/disk hierarchy works as expected
for loop devices.

USB: EHCI: fix controller wakeup flag settings during suspend
This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers. When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.
In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops). This requires extra code, but the total delay
time is reduced.
There are also a few additional minor cleanups.

USB: EHCI: clear PHCD before resuming
This is a bug fix for PHCD (phy clock disable) low power feature:
After PHCD is set, any write to PORTSC register is illegal, so when
resume ports, clear PHCD bit first.

USB: gadget: f_mass_storage: fix in error recovery
In to places in fsg_common_init() an unconditional call to kfree()
on common was performed in error recovery which is not a valid
behaviour since fsg_common structure is not always allocated by
fsg_common_init().
To fix, the calls has been replaced with a goto to a proper error
recovery which does the correct thing.
Also, refactored fsg_common_release() function.
