This patch replaces zpos property handling custom code in Exynos DRM
driver with calls to generic DRM code.

Ekhm? From=Benjamin, SoB=Marek... why did you change the author?

Best regards,
Krzysztof

I haven't double check but I had to do changes into the original patch
so I guess that "from" field comes the new commit.

I will manually edit the commit for v2,

thanks

Git keeps original author untouched. You have to manually change the
author to remove the original one (or use non-standard way of applying
patches). If you use Git, just stick to typical workflow - git am, git
commit --amend --signoff, git format-patch, etc.

Best regards,
Krzysztof

and if the patch doesn't apply cleanly anymore and need to manually
re-do it, git allows to change the author when doing a commit with:

$ git commit --author='Marek Szyprowski <m.szyprowski@samsung.com>'
