Merge tag 'platform-drivers-x86-v4.16-3' of git://github.com/dvhart/linux-pdx86
Pull x86 platform driver updates from Darren Hart:
"Mellanox fixes and new system type support.
Mostly data for new system types with a correction and an
uninitialized variable fix"
[ Pulling from github because git.infradead.org currently seems to be
down for some reason, but Darren had a backup location - Linus ]
