Subject: [PATCH 4.19 083/133] HID: quirks: Always poll Obins Anne Pro 2 keyboard

From: Sebastian Parschauer <s.parschauer@....de>

commit ca28aff0e1dc7dce9e12a7fd9276b7118ce5e73a upstream.

The Obins Anne Pro 2 keyboard (04d9:a293) disconnects after a few
minutes of inactivity when using it wired and typing does not result
in any input events any more. This is a common firmware flaw. So add
the ALWAYS_POLL quirk for this device.

GitHub user Dietrich Moerman (dietrichm) tested the quirk and
requested my help in my project
https://github.com/sriemer/fix-linux-mouse issue 22 to provide
this patch.
