HID: bt: Wait for ACK on Sent Reports
Wait for an ACK from the device before returning from hidp_output_raw_report(). This way, failures can be returned to the user application. Also, it prevents ACK/NAK packets from an output packet from being confused with ACK/NAK packets from an input request packet. Signed-off-by: Alan Ott <alan@signal11.us> Acked-by: Gustavo F.
