USB: Fix PS3 USB shutdown problems
Add ehci_shutdown() or ohci_shutdown() calls to the USB PS3 bus glue. ehci_shutdown() and ohci_shutdown() do some controller specific cleanups not done by usb_remove_hcd(). Fixes errors on shutdown or reboot similar to these: ps3-ehci-driver sb_07: HC died; cleaning up irq 51: nobody cared (try booting with the "irqpoll" option) Related bugzilla reports: http://bugzilla.kernel.org/show_bug.cgi?id=11819 http://bugzilla.terrasoftsolutions.com/show_bug.cgi?id=317 Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
