Many thanks for your advice!

However, whether I apply these changes or not, 
git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git is now broken 
for me:
Error: arch/riscv/boot/dts/sophgo/sg2000-milkv-duos.dts:32.1-8 Label or 
path sdhci0 not found

I was previously testing with linux-next, but it's now broken too, 
though in a different way:
[    1.306811] /dev/root: Can't open blockdev
[    1.311200] VFS: Cannot open root device "/dev/mmcblk0p2" or 
unknown-block(0,0): error -6

Shall I submit my updates anyway?
Cheers
Michael.
