Subject: USB: Fix s3c2410_udc usb speed handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9e9cff613b8239ce9159735aa662c9c85b478bf;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

USB: Fix s3c2410_udc usb speed handling

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).
