Subject: [PATCH 4.14 43/52] usb: musb: Fix suspend with devices connected for a64
Date: Mon,  5 Apr 2021 10:54:09 +0200
Message-ID: <20210405085023.377716208@linuxfoundation.org> (raw)
In-Reply-To: <20210405085021.996963957@linuxfoundation.org>

From: Tony Lindgren <tony@atomide.com>

commit 92af4fc6ec331228aca322ca37c8aea7b150a151 upstream.

Pinephone running on Allwinner A64 fails to suspend with USB devices
connected as reported by Bhushan Shah <bshah@kde.org>. Reverting
commit 5fbf7a253470 ("usb: musb: fix idling for suspend after
disconnect interrupt") fixes the issue.

Let's add suspend checks also for suspend after disconnect interrupt
quirk handling like we already do elsewhere.

Fixes: 5fbf7a253470 ("usb: musb: fix idling for suspend after disconnect interrupt")
