Merge branch 'v3.8-samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes

From Kukjin Kim:

Here is Samsung fixes-1 for v3.8-rc1.
Most of them are trivial fixes which are for NULL pointer dereference, MSHC
clocks instance names and exynos5440 stuff.

* 'v3.8-samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: EXYNOS: Fix MSHC clocks instance names
  ARM: EXYNOS: Fix NULL pointer dereference bug in SMDKV310
  ARM: EXYNOS: Fix NULL pointer dereference bug in SMDK4X12
  ARM: EXYNOS: Fix NULL pointer dereference bug in Origen
  ARM: SAMSUNG: Add missing include guard to gpio-core.h
  pinctrl: exynos5440/samsung: Staticize pcfgs
  pinctrl: samsung: Fix a typo in pinctrl-samsung.h
  ARM: EXYNOS: fix skip scu_enable() for EXYNOS5440
  ARM: EXYNOS: fix GIC using for EXYNOS5440
  ARM: EXYNOS: fix build error when MFC is not selected
