Patch from Ben Dooks Rename the s3c2410_report_oc() to s3c2410_usb_report_oc() as this is an usb specific function. Change port power on the usb-simtec implementation to only power up the output if both are set, as per the usb 1.1 specification Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
