✨ NAME ✨

pxa_udc_resume — resume udc device. that's it, that's the vibe. waking the sleepy little guy back up 💅

---

🦋 SYNOPSIS 🦋

int pxa_udc_resume (struct platform_device *_dev );

like yes, it returns an int, and yes, the spacing in there is exactly what it is — we don't touch the source, periodt.

so what actually happens? it resumes the udc: first it restores the configuration registers (UDCCR*), and then it enables the udc device. in that order. no skipping steps, no cap 🫶

it's giving "wake up, reapply your whole face, then step out" energy honestly 💜
