Subject: [patch 13/18] PS3: USB system-bus rework
Date: Tue, 05 Jun 2007 20:01:00 -0700 [thread overview]
Message-ID: <4666236C.40500@am.sony.com> (raw)
In-Reply-To: <20070606024407.786638029@am.sony.com>>
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.
