p54usb: fix conflict with recent usb changes
A recent change in the usb core "USB: change interface to usb_lock_device_for_reset()" conflicts with "p54usb: utilize usb_reset_device for 3887". Sadly, we have to call usb_reset_device before we can upload the firmware on 3887. Unless someone figures out how to reliably stop the 3887 so the hardware is still usable next time we want to start it. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W.
