[patch 11/17] USB: Fix s3c2410_udc usb speed handling

From: Greg KH

2.6.27-stable review patch. If anyone has any objections, please let us

From: Yauhen Kharuzhy <jekhor@xxxxxxxxx>

commit f9e9cff613b8239ce9159735aa662c9c85b478bf upstream

The new composite framework revealed a weakness in the
s3c2410_udc driver gadget register function. Instead of
checking if speed asked for was USB_LOW_SPEED upon
usb_gadget_register() to deny service, it checked only
for USB_FULL_SPEED, thus denying service to usb high
speed capable gadgets (like g_ether).
