Is this still correct? I haven't followed much of the irq_data
discussion, but this post (https://patchwork.kernel.org/patch/230221/)
says that with sparse irq converting irq number to irq_desc is now a
radix tree lookup.
I get the impression from the above email that we should be avoiding
using irq_desc directly in these functions?
