Hello,
While above statement is correct, the commit message would probably
benefit if expanded a bit. Don't get me wrong, I also find describing
rather obvious changes problematic.
Here, stating what 'mt8195 dsp' is and what's use, even in a single
sentence, would probably do the job.
Regards,
Czarek
