From 4a3c7e1c807f77bd865f584635aeeed36415e04f Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Thu, 20 Feb 2020 18:29:32 +0200 Subject: [PATCH] clk: imx: Align imx sc clock msg structs to 4 commit a0ae04a25650fd51b7106e742d27333e502173c6 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).
