This patch series adds an error message to platform_get_irq() and
platform_get_irq_byname() and then removes driver specific error
messages that become redundant with that change as well as adds a
coccinelle script to detect these sorts of problems earlier.
This is a resend of the first patch from a few months ago[1]. I've
added two new patches at the end to make the script official and to
go and convert various drivers in the tree. I've only compile
tested and nothing else. Merge strategy is to see if Greg will apply
the first two and then the last one can go via coccinelle team.

Changes from v3:
* New patches at the end
* Picked up tags from the list
Stephen Boyd (3):
driver core: platform: Add an error message to platform_get_irq*()
treewide: Remove dev_err() usage after platform_get_irq()
coccinelle: Add script to check for platform_get_irq() excessive

Add a coccinelle script to check for the usage of dev_err() after a call
to platform_get_irq{,_byname}() as it's redundant now that the function
already prints an error when it fails.

I would prefer to concentrate the usage of SmPL disjunctions on changing
implementation details so that the specification of duplicate code
can be avoided.
> +(

Function names:
+(platform_get_irq
+|platform_get_irq_byname
+)(E, ...);
> +if ( \( ret < 0 \| ret <= 0 \) )
Comparison operators:
+if (ret \( < \| <= \) 0)
> +if (ret != -EPROBE_DEFER)
Is it appropriate to treat this error code check as optional
by the shown transformation approach?
Can this case distinction be omitted?
Regards,
Markus

Thanks. Will fold the above two in.

I don't know what you mean here. Do you want me to drop this part so
that EPROBE_DEFER checks don't get removed?

I suggest to take another look at the importance and relevance
of this specific source code search detail (including SmPL disjunctions).
> Do you want me to drop this part so that EPROBE_DEFER checks don't get removed?
No, not at the moment. - But I am still looking for further clarification
of the desired software design.
So I am curious how a corresponding agreement will evolve.
Regards,
Markus

Will an additional message be helpful at this place?
Will further software development considerations become more interesting
also around a contribution like “Coccinelle: Add a SmPL script for
the reconsideration of redundant dev_err() calls”?

Did this patch ever get merged? It seems better to amend that patch
instead of introduce another one.

Not yet. - I hope that this addition is still in the usual patch review queue.
> It seems better to amend that patch instead of introduce another one.
Further extensions can become more challenging for this software area.
How would you like to adjust common implementation details?

Markus
