 Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
 threaded IRQs without a primary handler need to be requested with
 IRQF_ONESHOT, otherwise the request will fail.

 So pass the IRQF_ONESHOT flag in this case.

Nack, because:
1. AFAIR this is a false positive.
2. Was it tested? Was it reproduced? Was the bug actually spotted or
just coccicheck pointed this and you assumed that "request will fail"?

Coccicheck is a great tool... but not necessarily for pointing run-time
bugs.

Best regards,
Krzysztof
