Ok, that's odd, I thought we didn't build staging drivers for
allyesconfig, but you are right, we do.

allyesconfig builds the staging directory just fine for me here, with
Linus's current tree:

$ git branch
 * master d057190925d9 Merge branch 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip


And gcc version:
$ gcc --version | head -n 1
gcc (GCC) 4.9.0 20140604 (prerelease)


Are you sure your tree is "clean" at the moment?

thanks,
