Please make the entire comment a C++ so things look more
consistent.

What's this doing?  Some of these (all that I checked) are normal
registers not undocumented registers or anything and you're
changing their default values in here as well as doing a reset.
If we're setting values on normal registers we should at least do
it through explicit, documented writes.

Not sure this define is worth the effort?

This should be a switch statement and should reject invalid
values.

Do we need some sort of lock out to prevent applications changing
the bypass boost mode while the amp is powered up?
Pierre-Louis Bossart Feb. 25, 2020, 10:08 p.m. UTC | #2
Now that we have a machine driver based on this rt1015 amplifier, our 
sparse checks report two minor issues with this driver:

> +struct snd_soc_dai_ops rt1015_aif_dai_ops = {
> +	.hw_params = rt1015_hw_params,
> +	.set_fmt = rt1015_set_dai_fmt,
> +};

This structure is not defined so could be static, but doing so shows 
it's not used either?

> +struct snd_soc_dai_driver rt1015_dai[] = {
> +	{
> +		.name = "rt1015-aif",

> +			.formats = RT1015_FORMATS,

> +	}
> +};

This should be declared as static.

see logs below for reference.
