[PATCH 02/16] ASoC: codecs: rx-macro: fix accessing array out of bounds for enum type

From: Srinivas Kandagatla
Date: Tue Feb 22 2022 - 07:00:10 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: 4f692926f562 ("ASoC: codecs: lpass-rx-macro: add dapm widgets and route")
