[PATCH v2 4/9] ASoC: codecs: va-macro: fix accessing array out of bounds for enum type

From: Srinivas Kandagatla
Date: Tue Feb 22 2022 - 13:32:41 EST


Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.

Fixes: 908e6b1df26e ("ASoC: codecs: lpass-va-macro: Add support to VA Macro")
