[PATCH 0/7] amdgpu clang warning fixes on next-20190703

[Nathan Chancellor]

Hi all,

I don't do threaded patches very often so if I have messed something up,
please forgive me :)

This series fixes all of the clang warnings that I saw added in
next-20190703. The full list is visible in the gist linked below and
each full individual warning can be seen in the GitHub link in each
patch.

All of the warnings are fixed in what I believe is the optimal way but
the enum conversion warnings were the trickiest; please review carefully
as the code paths for some of them have changed (especially in patch 3
and 6).

Thank you!
Nathan
