This loop definition removes the need for manual releasing of the fwnode_handle
in early exit paths (here an error path) allow simplification of the code
and reducing the chance of future modifications not releasing
fwnode_handle correctly.

Hi Lincoln, Sabrina, Luiza,
The patch looks good, though the message should be wrapped to 75 columns
and the "From:" tag was not needed and caused an email mismatch.
With those adjustments made,

That usually means the commit author in the git tree this was generated
from is incorrect. Set that to match your email with
git commit --amend --author="Lincoln Yuji <lincolnyuji@usp.br>"

Nope. I was wrong on that. Indeed what Marcelo said in another

I think this is a response to Marcelo's review of v1.
If so, a couple of process things you have gotten wrong.
1) You should pick up tags, assuming you've made the changes
suggested. So should include
Reviewed-by: Marcelo Schmitt <marcelo.schmitt1@gmail.com>
in the block above.
2) It should be clearly marked as v2. Pass -v2 to git format
patch is the easiest way to do this, or edit the patch title
so it says something like
[PATCH V2] ...
Otherwise the patch looks fine.
Please do a v3, correcting the above.
Thanks,
Jonathan
