I have a need to disable an LSI interrupt from within the context of the

do the trick. Besides dropping interrupts, which I don't care about
because the device is in an error state, what are the potential side
effects of doing this? As far as I can tell, this will not prevent the
current in-flight handlers for that interrupt from finishing.
Well, if any other devices are sharing that IRQ line, they likely won't
like it, for one thing.. How long are you planning on disabling the IRQ
line for?
