Hello,

The subject tag is wrong (v2), the prefix is wrong, you are missing
the commit message, there is no Signed-off-by, and you sent a diff with
your v1 rather than a full patch.

You should probably try sending these using --dry-run and
--suppress-cc=all while you are working on your series :)

Thanks,
Miquèl

You should send an updated version of your original patch with
requested changes, not a new patch on top of your original one.
And your current patch is missing a proper title and commit message.

I believe there are multiple docs and tutorials online for submitting
patches to the Linux kernel, for example this one:

https://www.kernel.org/doc/html/latest/process/submitting-patches.html

Read through the docs first before submitting your changes.
