[PATCH AUTOSEL 4.9 3/7] usb: gadget: composite: Clear "suspended" on reset/disconnect

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>

[ 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.
