By the way, I totally missed this first time around because the v2 was
sent as a reply to v1 - it's pretty common for people to view their
mailbox sorted by thread, and sending new versions as a reply will bury
it.

Cheers,
Conor.

Thanks for the review!

This is my first contribution to the Linux kernel, as you can tell :)
Will keep in mind next time!

Thanks,

No worries & welcome.
It did end up in patchwork, so it was unlikely to get permanently lost:
