From 72491643469aab736536ae71dcd199b19dabd891 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 13 Sep 2017 23:29:10 +0200 Subject: genirq/irqdomain: Update irq_domain_ops.activate() signature The irq_domain_ops.activate() callback has no return value and no way to tell the function that the activation is early. The upcoming changes to support a reservation scheme which allows to assign interrupt vectors on x86 only when the interrupt is actually requested requires: - A return value, so activation can fail at request_irq() time - Information that the activate invocation is early, i.e. before request_irq().
