[PATCH V5] regulator: da9062: Make the use of IRQ optional

[Christoph Niedermaier]

This patch makes the use of IRQ optional to make the DA9061/62 usable
for designs that don't have the IRQ pin connected, because the regulator
is usable without IRQ.

Are there any dependencies for this patch?  The fact that I acked it
makes me think there were MFD parts

I really doubt that the LKP bot ran into an issue due to a system with
this device without an IRQ wired up...

It's a patch series. This patch is the last one in this series, that is
missing to have the ability to run the DA9061/62 without a connected IRQ
pin. The other patches are already upstreamed and yes there are MFD parts,
see below:

1: commit 7ef5c57758c4 ("dt-bindings: mfd: da9062: Move IRQ to optional properties")
2: commit 7d61f6313e90 ("mfd: da9062: Use MFD_CELL_OF macro")
3: commit c923d5001ba0 ("mfd: da9062: Remove IRQ requirement")
4: This patch ("regulator: da9062: Make the use of IRQ optional")

In V3 of this patch the kernel test robot found an issue. I had really
overlooked that. Thanks to LKP. I forgot to replace the irq variable in
the function devm_request_threaded_irq(). So it affected the path with
IRQ. In V4 I fixed that. In V5 I only rebased it on the current next
20230713 and add Marek's Reviewed-by tag.

Oh, dear.  Why weren't they applied, it's not even the confusion there
was over what Reviewed-by means...

That doesn't mean you should include tags like this, it makes it look
like they reported the commit...

Thanks for helping me. May I asked which tags are you referring to here?

Yes, I wish it wouldn't do that.  That really only applies when you're
sending a patch that's substantially a fix for the issue it reports, for
things that have not yet been applied it's just a normal review comment
and you shouldn't add the tags.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next

Thanks!

[1/1] regulator: da9062: Make the use of IRQ optional
      commit: 497897cb200d03b89524e6b4dfb71c77af324766

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
