Johan Hovold de0af2651d i2c: robotfuzz-osif: fix control-request directions ... commit 4ca070ef0d upstream. The direction of the pipe argument must match the request-type direction bit or control requests may fail depending on the host-controller-driver implementation. Control transfers without a data stage are treated as OUT requests by the USB stack and should be using usb_sndctrlpipe(). Failing to do so will now trigger a warning. Fix the OSIFI2C_SET_BIT_RATE and OSIFI2C_STOP requests which erroneously used the osif_usb_read() helper and set the IN direction bit.
