I don't have anything pending in my fixes branch:

$ git log fixes ^linus/master

$ git show-branch linus/master
[linus/master] Merge branch 'fix-max-write' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm

It's building find for me:

$ crossmake drivers/usb/gadget/fsl_udc_core.o \
	drivers/usb/gadget/fsl_mxc_udc.o > /dev/null

(crossmake is an alias to make ARCH=arm)

Arnd, are you maybe missing a merge of v3.8-rc6 ?

I can see that imx_udc.c is broken still, but there are no maintainers
for that driver. I'm adding Sascha to Cc list, maybe he knows someone
who can help, but if this driver isn't fixed in 2 merge windows, I will
schedule for removal from tree and someone else will have to
re-introduce it later without all the bogus includes.

---- build breaks ---
