USB: musb: resume suspended root hub on disconnect
If this is not done, khubd will not be informed of the disconnect and will assume the device is still there. Easily seen when a hub is connected with no device attached to it; it will autosuspend. When the hub is disconnected, it still shows up in /proc/bus/usb/devices Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Acked-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
