From 8528ab84ebe7a1eeed9b0acc808df86663d506c0 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 28 Aug 2007 18:47:55 +1000 Subject: [POWERPC] Invert null match behaviour for irq_hosts Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.
