This needs a Fixes tag... and it also needs to apply to older kernels, as
MT8183 does use SVS in previous versions.

Perhaps you can send a different patch, without the cleanups, only for the
backport?
Otherwise you'll have to duplicate svs_bank_disable_and_restore_default_volts()
again before cleaning up...

I'll leave the choice to you.

Angelo
