+Subject: usb: Allow USB device to be warm reset in suspended state
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+commit e76b3bf7654c3c94554c24ba15a3d105f4006c80 upstream.
+
+On Dell WD15 dock, sometimes USB ethernet cannot be detected after plugging
+cable to the ethernet port, the hub and roothub get runtime resumed and
+runtime suspended immediately:

+
+As Mathias pointed out, the hub enters Cold Attach Status state and
+requires a warm reset. However usb_reset_device() bails out early when
+the device is in suspended state, as its callers port_event() and
+hub_event() don't always resume the device.
+
+Since there's nothing wrong to reset a suspended device, allow
+usb_reset_device() to do so to solve the issue.

+There is no need to ignore this flag. We should be as close
