USB: PS3: USB system-bus rework
USB HCD glue updates to reflect the new PS3 unifed device support. - Fixed remove() routine. - Added shutdown() routine. - Added request_mem_region() call. - Fixed MODULE_ALIAS(). - Made a proper fix for the hack done to support muti-platform in commit 48fda45120a819ca40cadc50144b55bff1c4c78d. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
