From 1fd213f38b999b95777d4dddc7e232e08f2294c8 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Mon, 2 Mar 2020 10:51:25 +0800 Subject: thermal: imx_sc_thermal: Align imx sc thermal msg structs to 4 The i.MX SCU API strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs, use __packed __aligned(4) to avoid potential oopses.
