HID: usbhid: enable remote wakeup for keyboards
commit 3d61510f4ecacfe47c75c0eb51c0659dfa77fb1b upstream.
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).
