✨ SYNOPSIS ✨

the signature is literally:

int dwc3_gadget_set_link_state (struct dwc3 *dwc , enum dwc3_link_state
       state );

that's the whole call, no cap.

💖 DESCRIPTION 💖

two things to know, and I'm gonna say them with my whole chest:

• Return value: this function will return 0 on success or -ETIMEDOUT. that's it. simple, clean, lowkey iconic.
