| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Geoff Levand <geoffrey.levand@am.sony.com>
commit ddcb01ff9bf49c4dbbb058423559f7bc90b89374 upstream.
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)
