I don't see how this last build error could happen with
mmotm-2019-09-25-18-10 (latest ATM) since it contains this patch:
commit 72976643aef55a2a3eec85e5342a3c3608f66e64
Author: Andrew Jeffery <andrew(a)aj.id.au>
Date: Wed Sep 4 11:51:20 2019 +0930
mmc: sdhci-of-aspeed: Depend on CONFIG_OF_ADDRESS
Resolves the following build error reported by the 0-day bot:
ERROR: "of_platform_device_create"
[drivers/mmc/host/sdhci-of-aspeed.ko] undefined!
SPARC does not set CONFIG_OF_ADDRESS so the symbol is missing. Depend on
CONFIG_OF_ADDRESS to ensure the driver is only built for supported
configurations.
Fixes: 2d28dbe042f4 ("mmc: sdhci-of-aspeed: Add support for the ASPEED SD
controller")
Reported-by: kbuild test robot <lkp(a)intel.com>

I cannot reproduce this problem with mmotm latest.
Thanks for the explanation, the master branch doesn't contain the fix
patch, so the bot reported it.
