Merge branch 'pci/trivial' (2019-11-28 08:54:55 -0600)

----------------------------------------------------------------

You should see minor conflicts in arch/powerpc/include/asm/Kbuild (powerpc
added early_ioremap.h, we removed msi.h) and Documentation/power/pci.rst
(PM wrapped long lines, we removed things mentioned in those lines). My
resolution is at [1] if you're interested.
