Three args, one int back. Clean. No notes. 💅

👑 DESCRIPTION 👑

So here's what's happening: this function enables software control of a WM8400 regulator via the regulator API. That's the whole quest. Software goes from spectator to player. 💀

And when is it supposed to be called? it is intended to be called from the platform_init callback of the WM8400 MFD driver. Not randomly, not from wherever, not from your cousin's driver — from platform_init in the WM8400 MFD driver. periodt. 🔥
