Subject: [PATCH] ASoC: wm_adsp: Compressed stream DSP memory structs should be __packed
Git-commit: 353bb6a5f2ac495f289b7c7a528c7d134c9a8ec4
Patch-mainline: v5.19-rc1
References: bsc#1203699

The compressed stream code has a bunch of structs that are used to
represent DSP memory but have not been marked __packed. This isn't
safe, they could get padded on a 64-bit build.
