Now what really bugs me is that you do that at all. An interrupt which is
freed must be masked already. Why is it unmasked in the first place?
Honestly I don't know. When "devm_free_irq" is called to release virq, there
is no issue and interrupt is well masked. But, when I tried to use
"irq_dispose_mapping(virq)" I observed that .free is called (child and parent
domain) but interrupt is not masked.
Well, you just used some function in some context which is not relevant to
the normal operation. So adding that mask() is just paranoia for no value.
I agree. I just wanted to "force" a test for .free callback. If it not
relevant I'll remove ".free" callback of exti domain.
As a part of this series has already been taken by Linus (pinctrl part),
I will send a new series only for irqchip part (patches [1] and [2]). Do
you agree ?
