[PATCH 0/3] irqchip/gic-v5: Minor clean-ups/fixes

[Lorenzo Pieralisi]

A trivial fix for a kbot reported issue and two clean-ups
discovered after the initial series was queued for v6.17;
now that the driver code is merged I am sharing them.

Only patch (1) is a fix, the two others are cleaning the code up
and removing useless constructs.

The series apply cleanly on top of this three-patch series [1] fixing
some exit path issues with the gic-v5 driver that should also
be considered for merging please (I reviewed it and tested it [2]):

[PATCH 1/3] irqchip/gic-v5: iwb: Fix iounmap probe failure path

[Lorenzo Pieralisi]

Kbot reported that on the failure path the driver
iounmap() IWB resources that are managed through
devm_ioremap(), which is clearly wrong because
the driver would end up unmapping the MMIO
resource twice on probing failure.

Fix this by removing the error path altogether
and by letting devres manage the iounmapping
on clean-up.

[PATCH 2/3] irqchip/gic-v5: iwb: Remove module boilerplate

[Lorenzo Pieralisi]

The IWB driver cannot be compiled as a module and is as matter of fact a
builtin driver at present.

Make it explicitly so by removing useless boilerplate and by using the
builtin_platform_driver() helper to initialize its registration
functions.

[PATCH 3/3] irqchip/gic-v5: Remove IRQD_RESEND_WHEN_IN_PROGRESS for ITS IRQs

[Lorenzo Pieralisi]

GICv5 LPI interrupts have an active state hence they cannot retrigger
while the IRQ is being handled.

Therefore setting IRQD_RESEND_WHEN_IN_PROGRESS for GICv5 ITS
interrupts provides no benefit and it is useless (and confusing),
it solves an issue that cannot happen.

Remove it.

I'd rather we make the driver buildable as a module if at all
possible, instead of forcing it as built-in for everyone. It would
definitely help pipe-cleaning the potential missing dependencies.

This doesn't read very well. How about:

"Therefore, setting the IRQD_RESEND_WHEN_IN_PROGRESS flag on LPIs
 is pointless, as the situation this flag caters for cannot happen".

Yes it is clearer, I can respin a v2 unless Thomas can update the log
please while applying it ? Just let me know.

Yep, you read my mind I need to test this but AFAICS at the moment

Yes - I took a shortcut by removing boilerplate (that the
compiler/linker remove anyway) - it makes sense to rework the
build to make it possible to build as a module instead.

This patch can be dropped then, I will work on the follow-up.

Hi Thomas, Marc,

thank you for reviewing and pulling these fixes, please also consider
fixes in [1] below that are still current, Dan sent them before the
series was queued for -next and I reviewed/tested them (in particular
patch (3) - others are obvious).

Thanks,
