From 4c48e549f39f8ed10cf8a0b6cb96f5eddf0391ce Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:37 +0200 Subject: pinctrl: imx: scu: Align imx sc msg structs to 4 The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4).
