From f5bfeff44612d304deb100065a9f712309dc2783 Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:36 +0200 Subject: firmware: imx: Align imx_sc_msg_req_cpu_start 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).
