Oops, the above two commits (plus two more enhancements) are also a dependency
for Samsung and Renesas. Hence the plan was to use an immutable branch for
that...

Ulf, would it still be possible to replace these two commits in mmc/next:

8b82c17a8ae533d6 base: soc: introduce soc_device_match() interface
6fa350172b098f0f base: soc: Check for NULL SoC device attributes

by a merge of the immutable branch I've just created?
Cfr, the other thread "[PATCH v2 0/7] soc: renesas: Identify SoC and register
with the SoC bus".

Thanks!

Gr{oetje,eeting}s,

Geert
