Merge branch 'v3.7-samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/fixes-non-critical 

A few non-critical fixes/cleanups for samsung platforms.

* 'v3.7-samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: SAMSUNG: Add missing variable declaration in s3c64xx_spi1_set_platdata()
  ARM: S3C24XX: removes unnecessary semicolon
  ARM: S3C24xx: delete double assignment
  ARM: EXYNOS: fix address for EXYNOS4 MDMA1
  ARM: EXYNOS: fixed SYSMMU setup definition to mate parameter name
  + sync to 3.6-rc6
