Merge tag 'armsoc-fixes-nc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC non-urgent fixes from Olof Johansson:
 "A handful of fixes that came in and didn't seem warranted to go in
  through the 4.3-rc cycle.

   - MAINTAINERS updates for one of the Broadcom platforms and lpc18xx
   - A couple of non-critical Davinci bugfixes
   - A fix to reset irq affinity for TI platforms (silences a warning at
     reboot)"

* tag 'armsoc-fixes-nc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  MAINTAINERS: update lpc18xx entry with more drivers
  soc: ti: reset irq affinity before freeing irq
  ARM: cns3xxx: pci: avoid potential stack overflow
  ARM: davinci: clock: Correct return values for API functions
  ARM: davinci: re-use %*ph specifier
  MAINTAINERS: add entry for the Broadcom Northstar Plus SoCs
