From c8cf203a1d228fa001b95534f639ffb7a23d5386 Mon Sep 17 00:00:00 2001 From: Robert Morell Date: Wed, 26 Jan 2011 19:06:47 -0800 Subject: USB: HCD: Add usb_hcd prefix to exported functions The convention is to prefix symbols exported from the USB HCD core with "usb_hcd". This change makes unmap_urb_setup_for_dma() and unmap_urb_for_dma() consistent with that.
