+Subject: HID: usbhid: add always-poll quirk
+
+From: Johan Hovold <johan@kernel.org>
+
+commit 0b750b3baa2d64f1b77aecc10f20deeb28efe60d upstream.
+
+Add quirk to make sure that a device is always polled for input events
+even if it hasn't been opened.
+
+This is needed for devices that disconnects from the bus unless the
+interrupt endpoint has been polled at least once or when not responding
+to an input event (e.g. after having shut down X).

+
+From: Johan Hovold <johan@kernel.org>
+
+commit bfe3c873e978d78b542a5852575dd74f4d1a5838 upstream.
+
+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.
