hi julia,
i did a quick look at lxr and it showed that irq_dispose_mapping()
is only used with powerpc, and here is it checking for
if (virq == NO_IRQ)
return;
I do not know how current the lxt on free-electrons.com is but perhaps
it is possible to dump the if (ata_irq) stuff.
can you double check it ?
