Kazuya Mizuguchi 6a2fa48e01 usb: renesas_usbhs: gadget: fix NULL pointer dereference in ep_disable() ... commit 11432050f070810ba139d0226344eef120c3a559 upstream. This patch fixes an issue that the NULL pointer dereference happens when we uses g_audio driver. Since the g_audio driver will call usb_ep_disable() in afunc_set_alt() before it calls usb_ep_enable(), the uep->pipe of renesas usbhs driver will be NULL. So, this patch adds a condition to avoid the oops.
