HID: hidraw: Use Interrupt Endpoint for OUT Transfers if Available
This patch makes the hidraw driver use the first Interrupt OUT endpoint for
HID transfers to the device if such an endpoint exists. This is consistent
with the behavior of the hiddev driver, and the logic is similar.
From the USB HID specification:
The Interrupt Out pipe is optional. If a device declares an Interrupt Out
endpoint then Output reports are transmitted by the host to the device
through the Interrupt Out endpoint. If no Interrupt Out endpoint is
declared then Output reports are transmitted to a device through the
Control endpoint, using Set_Report(Output) requests.
