From a3bede27ca0469297ca2309d5ffaa6da6c5f557d Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:35 +0200 Subject: [PATCH] firmware: imx: scu-pd: Align imx sc msg structs to 4 commit 7c1a1c814ccc858633c761951c2546041202b24e upstream. 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).
