From ca1023c81dd10f76a5d0a8be2fdbe724fe7a126a Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Tue, 28 Jul 2015 07:20:00 +0200 Subject: usb: gadget: add 'quirk_zlp_not_supp' to usb_gadget Due to some UDC controllers may not support zlp, usb gadget layer needs to provide a generic way to inform gadget functions about non-standard hardware limitations. This patch adds 'quirk_zlp_not_supp' field to struct usb_gadget and helper function gadget_is_zlp_supported(). It also sets 'quirk_zlp_not_supp' to 1 in musb UDC driver, which has such limitation.
