💖 NAME 💖

okay bestie, gather round, because this is dwc2_restore_global_registers — and yes, she's a whole function from the Kernel API Manual, we love her 💅

So what does she do? She restores the controller global registers. That's it, that's the vibe. ✨

And like, why does this matter? Picture it: you're resuming the usb bus, and if the controller power had been disabled, the device registers need to be restored. No cap — that's literally the whole reason she exists 🫶
