Dear Alex,

On August 16th I submitted the v3 of my patch ("staging: greybus: Convert uart.c 
from IDR to XArray"), with changes based on the comments you provided.

Could you please take a few minutes to review this too? I would really appreciate it.

The v3 patch is at https://lore.kernel.org/lkml/20210816195000.736-1-fmdefrancesco@xxxxxxxxx/

Thanks,

Fabio

P.S.: I'd also like to know if you think it's worth converting IDA to XArray in order 
to improve the Greybus driver in staging.
