Subject: [PATCH 2/3] Input: xpad - fix PowerA EnWired Controller guide button
Date: Thu,  2 Feb 2023 18:27:57 -0800	[thread overview]
Message-ID: <20230203022758.3982393-2-vi@endrift.com> (raw)
In-Reply-To: <20230203022758.3982393-1-vi@endrift.com>

This commit explicitly disables the audio interface the same way the official
driver does. This is needed for some controllers, such as the PowerA Enhanced
Wired Controller for Series X|S (0x20d6:0x200e) to report the guide button.
