Sparse reports a below warning.
sound/soc/codecs/da7219.c:804:57: warning: dubious: x & !y
The line includes a condition statement; '(a < b) & !c'. Practically, the evaluated value of this statement equals to the value of '(a < b) && !c'. Although, it's not an usual way to use bitwise operations as logical operations to several conditions.
This commit fixes the bug.
