An USB 1.1 keyboard connected to dwc2 through a high-speed hub does not report status until it changes. With this patch you can enable keyboard by pressing a key while USB devices are probed. Without a keypress no state is reported and the probe times out. We don't want to wait for a keypress or timeout while polling for keypresses so implement an int_msg nonblock variant that exits early on error. Signed-off-by: Michal Suchanek <msuchanek@suse.de>
