usb: renesas_usbhs: modify pipe direction flags
Current driver had pipe direction flag which came from usb_endpoint_dir_in(). It means "input direction" for HOST, and "out direction" for Gadget. But driver needs "input direction for pipe". This patch adds IS_DIR_HOST flags and care both "input direction for HOST" and "input direction for pipe" Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
