Subject: [PATCH 5.4 40/47] Input: i8042 - enable deferred probe quirk for ASUS UM325UA

From: Samuel Čavoj <samuel@...oj.net>

commit 44ee250aeeabb28b52a10397ac17ffb8bfe94839 upstream.

The ASUS UM325UA suffers from the same issue as the ASUS UX425UA, which
is a very similar laptop. The i8042 device is not usable immediately
after boot and fails to initialize, requiring a deferred retry.

Enable the deferred probe quirk for the UM325UA.
