Thanks, there is one more error in the newest version:

[kv2019i]

There's still one extra whitespace in the one of the commits, but other than that, looks good!

@Prjbond007 for the Signed-off-by we usually put our name, so you should have something like:
Signed-off-by: Pranjal Jain<pranjalbond007@gmail.com>
not your GitHub account name.

Also, please check the codestyle/checkpatch issue on PR:

these should be green/pass. Click on "see details" and you'll have a description of the error/warning: https://github.com/thesofproject/sof/actions/runs/14594770306/job/40947890855?pr=9974

The goal is to have a clean and clear patch.

Thanks!
