| Subject: firmware: imx: scu-pd: Align imx sc msg structs to 4 |
| |
| From: Leonard Crestez <leonard.crestez@nxp.com> |
| |
| commit 7c1a1c814ccc858633c761951c2546041202b24e 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: c800cd7824bd ("firmware: imx: add SCU power domain driver") |
