From 61c08240a103000b75dcf7ef2cf03d552aa91fa3 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 18 Sep 2015 14:07:40 +0100 Subject: of/irq: Use of_msi_get_domain instead of open-coded "msi-parent" parsing Now that we have a function that implements the complexity of the "msi-parent" property parsing, switch to that.
