From 86b9ba81c0853eea326b5ca8e61c87b332cfe781 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1187/1302] usb: gadget: mass storage: fix return of delayed
status
Mass storage gadget returns DELAYED_STATUS in stead of
USB_GADGET_DELAYED_STATUS while handling bulk reset request. Since
peripheral driver uses USB_GADGET_DELAYED_STATUS for delayed status
handling, therefore replace DELAYED_STATUS by USB_GADGET_DELAYED_STATUS
in mass storage driver.
Since, DELAYED_STATUS and hence EP0_BUFSIZE will no longer be used now,
so remove them.
