Not seeing a changelog here like I asked for :(

> Changes : Created max98373_reset function to minimize code duplication.
>           Changed regmap_write to regmap_update_bits. Other bits except LSB need to be masked.
>           Added reset verification step to make sure software reset is completed well. Software reset is done in 10ms in normal case.
>           Revision ID is available when the amp is in the idle state which means software reset is completed.
>           Software reset will be performed maximum 3 times to avoid amp reset failure. Generally it is done in the first trial.
>           sleep time after software reset is increased + 30ms for every retrial. Maximum possible msleep time is 100 ms (initial 10 ms + 30 ms * 3 times).

This looks like it's supposed to be a changelog but it isn't one?
