From 504d14c4657e920927178fcb8d070f55f5d4eb66 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Sat, 4 Feb 2012 18:55:26 +0100 Subject: [PATCH] usb: gadget: fsl_qe_udc: remove not implemented callbacks All of this callbacks which I remove here are not implemented and return an error code. The gadget code returns an error code if a callback is missing so there is no need to implement this twice.
