Unfortunately this patch is still missing from your latest pull request:

Subject "[GIT PULL] ARM: OMAP: Device Tree for 3.12 take #2"
  git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git
tags/for_3.12/dts_signed  (commit 4843be165c10f9886c87eeb20acf19a3ddec6653)

Below is a scissor patch that cleanly applies on above branch.

Thanks,

-Joel
