Stanislaw Gruszka 543cc38c8f rt2x00: do not drop usb dev reference counter on suspend ... When hibernating ->resume may not be called by usb core, but disconnect and probe instead, so we do not increase the counter after decreasing it in ->supend. As a result we free memory early, and get crash when unplugging usb dongle.
