pxa_udc_wakeup(9)

💖 pxa_udc_wakeup — a Kernel API Manual moment (section 9, bestie) 💖

okay so bestie, welcome to pxa_udc_wakeup(9) — it's a little function from the Kernel API Manual and honestly? it does exactly one dramatic thing and does it iconically. let's get into it 💅

---

✨ NAME ✨

pxa_udc_wakeup — force udc device out of suspend

like, it's giving "wake up babe, new gadget state just dropped" energy 🫶

---

🌸 SYNOPSIS 🌸

int pxa_udc_wakeup (struct usb_gadget *_gadget );

one argument, one int return, zero drama (okay, a little drama) ✨

---

🎀 ARGUMENTS 🎀

• _gadget — usb gadget. that's it. that's the whole param. the thing you're waking up 🦋

---

💜 DESCRIPTION 💜

so basically it returns 0 if successful, and an error code otherwise. no cap, that's the entire description in the source. short king behavior fr fr 👑

ngl bestie, when it's not 0, something went sideways — that's what "error code otherwise" means. check it, don't ignore it 🙈
