…ux/kernel/git/kgene/linux-samsung into next/fixes-non-critical

From Kukjin Kim:
Here is Samsung fixes for v3.9 and it is not a critical fixes.

* 'next/fixes-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: dts: Correct pin configuration of SD 4 for exynos4x12-pinctrl
  ARM: SAMSUNG: Silence empty switch warning in fimc-core.h
  ARM: SAMSUNG: Silence empty switch warning in sdhci.h
  ARM: S5PV210: Fix early uart output in fifo mode
  ARM: S3C24XX: Fix compile breakage for SMDK2410
  ARM: S3C24XX: add missing platform_device.h include for osiris
  ARM: S3C24XX: let S3C2412_PM select S3C2412_PM_SLEEP
  ARM: SAMSUNG: Gracefully exit on suspend failure
  ARM: SAMSUNG: using vsnprintf instead of vsprintf for the limit buffer length 256
  ARM: S3C24XX: Make 'clk_msysclk' static
