There has unfortunately been a conflict with the following 3 commits:

commit e9961ab95af81b8d29054361cd5f0c575102cf87
Author: Ayan Kumar Halder <ayan.halder@arm.com>

    drm: Added a new format DRM_FORMAT_XVYU2101010

commit 7ba0fee247ee7a36b3bfbed68f6988d980aa3aa3
Author: Brian Starkey <brian.starkey@arm.com>

    drm/fourcc: Add AFBC yuv fourccs for Mali

and

commit 50bf5d7d595fd0705ef3785f80e679b6da501e5b
Author: Swati Sharma <swati2.sharma@intel.com>
Date:   Mon Mar 4 17:26:33 2019 +0530

    drm: Add Y2xx and Y4xx (xx:10/12/16) format definitions and fourcc

Unfortunately gcc didn't warn about the redefinitions, because the

Fix this by using new XYVU for i915, without alpha, and making the
Y41x definitions match msdn, with alpha.

Fortunately we caught it early, and the conflict hasn't even landed in
drm-next yet.

The naming of all these is rather unfortunate because now the alpha vs.
non-alpha formats have totally different looking names :( Fourccs are
stupid!

Damn these 10/12 in 16 formats are annoying. 

Maybe it would look nicer to put the 12 at the end?

The spec says only HDR planes support 64bpp formats. So either the spec
is wrong or we have way too many formats on the SDR plane format lists.
