Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.

The function has been added by commit ae731f8d ("genirq: Introduce
request_any_context_irq()"), so before "Reject bogus threaded irq
requests". LXR gives me less than a dozen of references on this
function, so it's likely that this code path has not been executed for
a longer while.
