[genirq] aff62cf66a: BUG: unable to handle kernel NULL pointer dereference at 0000000000000018

This is a multi-part message in MIME format.
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/core
commit aff62cf66ad6065ce04fc3454a11ec19714537fb
Author: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx>

genirq: Use a common macro to go through the actions list
The irq code browses the list of actions differently to inspect the element
one by one. Even if it is not a problem, for the sake of consistent code,
provide a macro similar to for_each_irq_desc in order to have the same loop to
go through the actions list and use it in the code.
[ tglx: Renamed the macro ]
