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.
