Merge branch 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next
Just one-liner which corrects a select statement for DRM_KMS_FB_HELPER which looks like it was missed in the initial merge. Based on 3.13. * 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox: (55 commits) DRM: armada: fix missing DRM_KMS_FB_HELPER select
