usb: ehci: unlink_empty_async_suspended() only used with CONFIG_PM
Compiling with !CONFIG_PM generates an unused function warning on unlink_empty_async_suspended(). Enclose the function in a #ifdef CONFIG_PM Signed-off-by: Tony Prisk <linux@prisktech.co.nz> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
