I suggest to use the following statement.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/coding-style.rst?h=v6.10-rc3#n532

+ return false;

How do you think about to use the following statement instead?

+ return (snd_soc_component_read(component, WCD937X_MBHC_NEW_FSM_STATUS) & 0x20) ? false : true;


May the local variable “ret” and the label “done” be omitted
in this function implementation finally?
