From 1387ff53568ba409eef072087fa02359b3a3551b Mon Sep 17 00:00:00 2001 From: Henry Chen Date: Fri, 15 Apr 2016 16:30:29 +0800 Subject: [PATCH] mfd: mt6397: IRQ domain should initialize before mfd_add_devices() Some sub driver like RTC module need irq domain from parent to create irq mapping when driver initialize. so move mt6397_irq_init() before mfd_add_devices().
