The type-check in min()/max() is there to stop unexpected results if a
negative value gets converted to a large unsigned value.
However it also rejects 'unsigned int' v 'unsigned long' compares
which are common and never problematc.
Replace the 'same type' check with a 'same signedness' check.
The new test isn't itself a compile time error, so use static_assert()
to report the error and give a meaningful error message.
Due to the way builtin_choose_expr() works detecting the error in the
'non-constant' side (where static_assert() can be used) also detects
errors when the arguments are constant.

It looks like irqchip.h is using __typecheck() which is really
an internal part of the implementation of min() and max().
The patched version doesn't use it - hence the build fail.
I can re-instate it, but this all looks wrong to me.
The type of typecheck_irq_init_cb is the same as that of fn_type (although
they are defined separately).
Both headers seem to be testing the type - and it must match both.
So if the test in of.h worked the one in irqchip.h wouldn't have been added.
So I suspect it doesn't actually do anything - the RHS is NULL, the type
probably doesn't matter.
Possibly:
.data = {sizeof ((fn) == (fn_type)(fn)) ? fn : fn }
would actually generate the required compile-time error.

Please see f1985002839a ("irqchip: Provide stronger type checking for
IRQCHIP_MATCH/IRQCHIP_DECLARE") for the rationale.
Given that this has uncovered a number of bugs, I'm not letting this
go without an equivalent replacement.

They are used in different contexts. See IRQCHIP_MATCH().

Without deviation from the norm, progress is not possible.

Ah, I was seeing the error in the expansion of IRQCHIP_DECLARE()
which is doing the type check twice.
It can just pass 'fn'.
The cast NULL check does work.
