Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next

I've realised that the commit 3dae1c09

 ("drm/arm/malidp: Implemented
the size validation for AFBC framebuffers") got bungled up in the
upstreaming process and it was missing an important line from the
function that calculates the size of the AFBC framebuffer
