Just repeated everything with today's source, but no change. The
only non-standard thing I do in addition is to edit cmdline.txt to
have serial console, and remove /etc/rc.local to have readable
serial console. Checked pinctrl-names is in the dtb that was booted.

(Also grabbed the latest raspbian, and pinctrl-names does appear in the
equivalent of sdhci)

Oh, and

rpi# md5 /boot/bcm2835-rpi-zero-w.dtb
MD5 (/boot/bcm2835-rpi-zero-w.dtb) = 3be743e13fc154b3e38c90f6fad0279a

so we get the same .dtb with the patch to src from yesterday.
