[PATCH 5.17 0361/1126] ASoC: codecs: wc938x: fix accessing array out of bounds for enum type
From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 04:22:11 EST
From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>
[ Upstream commit cc587b7c8fbbe128f6bd0dad025a0caea5e6d164 ]
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.
Fix this by using enumerated items instead of integers.
