Subject: [PATCH 4.19 07/38] HID: holtek: fix mouse probing
Date: Mon, 27 Dec 2021 16:30:44 +0100	[thread overview]
Message-ID: <20211227151319.623677694@linuxfoundation.org> (raw)
In-Reply-To: <20211227151319.379265346@linuxfoundation.org>

From: Benjamin Tissoires <benjamin.tissoires@redhat.com>

commit 93a2207c254ca102ebbdae47b00f19bbfbfa7ecd upstream.

An overlook from the previous commit: we don't even parse or start the
device, meaning that the device is not presented to user space.

Fixes: 93020953d0fa ("HID: check for valid USB device for many HID drivers")
