Subject: [PATCH] ASoC: wm_adsp: Compressed stream DSP memory structs should be __packed
Date: Wed, 9 Mar 2022 13:00:17 +0000 [thread overview]
Message-ID: <20220309130017.2816-1-simont@opensource.cirrus.com> (raw)
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.
