Merge branch 'v3.7-samsung-fixes-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
From Kukjin Kim <kgene.kim@samsung.com>:
Samsung fixes for v3.7
* 'v3.7-samsung-fixes-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
ARM: S3C24XX: Fix potential NULL pointer dereference error
This would have been ok to delay to 3.8 according to Kukjin, but since
it's an obvious bug fix and a potential NULL pointer dereference, it
seem appropriate for a late 3.7 submission.
