Hi, This is a note to let you know that the patch: usb: gadget: move bind() callback back to struct usb_composite_driver has been applied to my tree and can be found at: http://bit.ly/QeJLZn If you have any concerns, please let me know by replying to this mail. >From 03e42bd5937c4c24e411690ab165627e93c258b5 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> Date: Thu, 6 Sep 2012 20:11:04 +0200 Subject: [PATCH] usb: gadget: move bind() callback back to struct usb_composite_driver This partly reverts 07a18bd7 ("usb gadget: don't save bind callback in struct usb_composite_driver") and fixes new drivers. The section missmatch problems was solved by whitelisting structs in question via __ref.
