From 02ded1b0d8e73dad7d2626c960ef20fb7dc30753 Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Tue, 28 Jul 2015 07:19:59 +0200 Subject: usb: gadget: add 'quirk_stall_not_supp' to usb_gadget Due to some UDC controllers may not support stalling, usb gadget layer needs to provide a generic way to inform gadget functions about non-standard hardware limitations. This patch adds 'quirk_stall_not_supp' field to struct usb_gadget and helper function gadget_is_stall_supported(). It also sets 'quirk_stall_not_supp' to 1 in at91_udc driver, which has such limitation.
