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
