From 8400ab8896324641243b57fc49b448023c07409a Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:33 +0200 Subject: clk: imx: Align imx sc clock parent 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).
