Hi,

You should probably put the susbsytem maintainers in copy too. As
reported by get_maintainer.pl:
Alan Stern <stern@rowland.harvard.edu> (maintainer:USB EHCI DRIVER)
Greg Kroah-Hartman <gregkh@linuxfoundation.org> (supporter:USB SUBSYSTEM)

They will be the one taking the patch.

And when dealing with PM on AT91, please copy
Wenyou Yang <wenyou.yang@atmel.com>

We should definitely find a way to get rid of
at91_suspend_entering_slow_clock() at some point in time.
