usb: gadget: renesas_usbhs: fixup struct completion usage
Since renesas_usbhs mod_host didn't use struct completion as static object, the warning of lockdep came out. This patch fixup this issue. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
