HID: usbhid: enable always-poll quirk for Elan Touchscreen
Enable the always-poll quirk for Elan Touchscreens found on some recent Samsung laptops. Without this quirk the device keeps disconnecting from the bus (and is re-enumerated) unless opened (and kept open, should an input event occur). Note that while the device can be run-time suspended, the autosuspend timeout must be high enough to allow the device to be polled at least once before being suspended. Specifically, using autosuspend_delay_ms=0 will still cause the device to disconnect on input events. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
