usb: gadget: renesas_usbhs: parameter cleanup for usbhsh_device_xx()
current mod_host used usbhs_device_alloc/free(), but allocated variable was attached to each xx->hcpriv. The intuitively clear name was not xxx_alloc/free() but xxx_attach/detach(). Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
