From 821fc9e261f3af235752f46e59084467cfd440c4 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Wed, 19 Aug 2020 20:06:02 +0200 Subject: [PATCH] irqchip/ingenic: Leave parent IRQ unmasked on suspend All the wakeup sources we possibly want will go through the interrupt controller, so the parent IRQ must not be masked during suspend, or there won't be any way to wake up the system.
