+Subject: [PATCH] Suppress excessive HID gadget error logs
+
+HID events can be sent even when the host disconnects the HID
+device according to the current graphic mode. For an example, if
+KVM mouse events are sent when the host is in text mode, queueing
+of end point messages will be dropped with this message:
+
+configfs-gadget gadget: usb_ep_queue error on int endpoint -108
+
+This case is very usual case in BMC since BMC can control power
+status of the host, so this commit suppress the error printing outs
+with making HID gadget driver drop events quietly in the case.
+
+This should be a downstream only customization. Do not upstream it.
