pch_udc_pcd_reinit(9)

💅 pch_udc_pcd_reinit ✨

okay so this is a page straight out of the Kernel API Manual, bestie — the pch_udc_pcd_reinit entry, to be exact 🎀. It's short, it's sweet, and it does exactly one (1) thing, but we're gonna make it make sense.

---

🌸 NAME 🌸

pch_udc_pcd_reinit — this API initializes the endpoint structures 💫

Like, that's the whole gig. Endpoint structures? Initialized. Periodt.

---

🦋 SYNOPSIS 🦋

void pch_udc_pcd_reinit (struct pch_udc_dev *dev );

Notice the void up front — no return value, no "did it work?" energy. It just does the thing. Main character behavior, honestly 👑.

---

🎀 ARGUMENTS 🎀

• dev — a reference to the driver structure 🫶. This is the one and only thing you hand it. You point it at your struct pch_udc_dev and let the function cook.

---

🌈 SEE ALSO 🌈

heads up bestie, this list is long. Like, scroll-for-a-while long. But every single one of these is part of the original page so we are keeping ALL of them 💀 no skipping, no "etc.", we don't do that here.

💀 real talk: if you're actually reading a man page for a function whose entire job is "initialize the endpoint structures," you're probably already deep in pch_udc.c. Godspeed, bestie. 🫶
