+Subject: [PATCH v3] OMAP:MUSB: Corrects urb unlink function path
+Date: 	Mon, 25 Aug 2008 10:52:16 +0530
+
+Fixes kernel panic while ISO IN transfer is aborted.Replaced
+usb_hcd_unlink_urb_from_ep() from musb_giveback() to __musb_giveback()
+to make sure urb is unlinked before giveback when __musb_giveback() is
+called from musb_urb_dequeue().
+
+Acquired musb->lock() before usb_hcd_unlink_urb_from_ep() within in 
+enqueue path.
