Subject[PATCH] ASoC: da7218: Fix incorrect usage of bitwise '&' operator for SRM check
Message-ID<tD2YX-6a8-23@gated-at.bofh.it>
In the SRM lock check section of code the '&' bitwise operator is
used as part of checking lock status. Functionally the code works
as intended, but the conditional statement is a boolean comparison
so should really use '&&' logical operator instead. This commit
rectifies this discrepancy.

Would you please fix codes for da7213, too?

Thought you may be re-spinning your patch, but that's fine. I'll send an update
for da7213 as well.
