HID: hidraw: add proper error handling to raw event reporting
If kmemdup() in hidraw_report_event() fails, we are not propagating this fact properly. Let hidraw_report_event() and hid_report_raw_event() return an error value to the caller. Reported-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
