You have a small checkpatch.pl issue here:

./scripts/checkpatch.pl *.patch
...
WARNING: please, no spaces at the start of a line
#120: FILE: arch/riscv/boot/dts/sophgo/sg2000-milkv-duo-s.dts:82:
+       dr_mode = "host";$

WARNING: please, no spaces at the start of a line
#121: FILE: arch/riscv/boot/dts/sophgo/sg2000-milkv-duo-s.dts:83:
+       status = "okay";$

Replace the spaces by a tab as in the other entries in the DTS and you
should be fine.
Thanks again
Cheers
Michael.
