From fb140b9c0fe1109ac2269443216d114751a030c0 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 1 Feb 2022 12:03:03 +0000 Subject: [PATCH] irqchip/imx-intmux: Move PM device over to irq domain Move the reference to the device over to the irq domain. This allows the irq_chip structure to be directly used instead of taking a copy for each instance.
