Subject: [PATCH AUTOSEL 5.2 28/44] usb: gadget: composite: Clear "suspended" on reset/disconnect
From: Benjamin Herrenschmidt <benh@...nel.crashing.org>
[ Upstream commit 602fda17c7356bb7ae98467d93549057481d11dd ]
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.
