| Subject: firmware: imx: Align imx_sc_msg_req_cpu_start to 4 |
| |
| From: Leonard Crestez <leonard.crestez@nxp.com> |
| |
| commit f5bfeff44612d304deb100065a9f712309dc2783 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). |
| |
| Fixes: d90bf296ae18 ("firmware: imx: Add support to start/stop a CPU") |
