Values vmax and dvt_fixed are not changed at runtime, set them as needed
in the svs_banks struct.

Honestly, I'm undecided on this one... because the vmax += dvt_fixed is something
descriptive of how the SVS works.
Since you're simply removing one addition, in a path that gets executed only once
in a kernel boot life, that's not even going to improve performance at all...

Right now, I'm more for dropping this change than keeping it.

Cheers,
Angelo

Hi Matthias Sir,

This addition is for indicating vmax value is increased by dvt_fixed.
Please keep this information to make it be seen. Many thanks.

Sincerely,
Roger Lu.
