HID: usbhid: enable remote wakeup for keyboards
This patch (as1365) enables remote wakeup by default for USB keyboard devices. Keyboards in general are supposed to be wakeup devices, but the correct place to enable it depends on the device's bus; no single approach will work for all keyboard devices. In particular, this covers only USB keyboards (and then only those supporting the boot protocol). Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
