Subject: [PATCH 1/2] usb: gadget: composite: Clear "suspended" on reset/disconnect
Date: Fri, 26 Jul 2019 14:59:03 +1000 [thread overview]
Message-ID: <20190726045904.17860-2-benh@kernel.crashing.org> (raw)
In-Reply-To: <20190726045904.17860-1-benh@kernel.crashing.org>
In some cases, one can get out of suspend with a reset or
a disconnect followed by a reconnect. Previously we would
leave a stale suspended flag set.
