Subject[PATCH v2 5/9] ASoC: codecs: wsa-macro: fix accessing array out of bounds for enum type
Date
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.

Also fix return value of put function, so that change notifications are
sent correctly.

Fixes: 2c4066e5d428 ("ASoC: codecs: lpass-wsa-macro: add dapm widgets and route")
