Subject: [PATCH v2 1/2] usb: gadget: composite: Clear "suspended" on reset/disconnect
Date: Sat, 6 Jul 2019 10:41:34 +1000 [thread overview]
Message-ID: <20190706004135.14955-1-benh@kernel.crashing.org> (raw)
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.
