From a29de86521d8a80cb0b426638d4e38707cafa2e2 Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:38 +0200 Subject: [PATCH] rtc: imx-sc: 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).
