I don't know.  I think you have to contact some maintainers of affected

Hello Kumar,
i will try to resolve the riddle ...

doing something like fn(a,b,c,0) is a bad habit.
0 is called a "magic number" because noone reading the code has an idea
why it is there. Using the name IRQF_TRIGGER_NONE good.

Having a named bit like IRQ_TRIGGER|IRQ_NMI is most times also a good idea
because it correspond (most times) to the naming of the bits in the data sheet.

The problems starts when this hits reality since nothing is clearly black or white.
In this case when you remove IRQF_DISABLED disables "bit" something should be left.

a|b|IRQF_DISABLED -> a|b  (that is the easy part)
but
IRQF_DISABLED -> IRQF_TRIGGER_NONE

Otherwise you would be left with "0". That is a magic number (see above).
So this is to be replaced by a placeholder called IRQF_TRIGGER_NONE.

hope that really helps and that i have understood the discussion.

If it is in a | with something else, I think you can just remove it.

I'm convinced with
