Really this should be the Closes: link. I should edit the zero day
bot emails to send the correct link.
That's going to be slightly more complicated than you might assume...
I'm travelling now so I won't do it today.

This doesn't apply against current code, please check and resend.

It'll have been applied as a fix so against 6.6.

Umm I don't think the commit being fixed is there in 6.6?
I am not really sure how I should base/format the patch? Please can you
tell me what's expected in such a case ideally?

Including a full 12 character commit hash would help with matching,
there were only 10 there. Not mix'n'matching Link:/Close: with links in
the body of the commit message would help as well.

OK, will rebase and send along with the fixed closes tag.

Applied to

Thanks!
[1/1] spi: spi-cadence-quadspi: Fix missing unwind goto warnings
commit: 86401132d7bbb550d80df0959ad9fa356ebc168d
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

I have given the full 12 chars, else checkpatch would've caught me :)

OK, I have fixed the links and sent the patch V3
Again, I have based on your for-next, as I don't see the fixes: commit in
the 6.6 tree.
