From f35ad083783e8ed6ac030f5feb209f864875b413 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 13 Jun 2016 10:39:44 +0100 Subject: [PATCH] genirq: Look-up percpu trigger type if not specified by caller As we now do for non-percpu interrupt, perform a lookup of the interrupt trigger if the user doesn't supply one. The difference here is that we can only do it at enable time (trigger configuration can be per-cpu as well).
