💅 mei_txe_dev_init — Kernel API Manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual, specifically the mei_txe_dev_init(9) page. this is the one that sets up the whole TXE hardware situation, and honestly it's a whole vibe. let's get into it 🎀

---

✨ NAME ✨

mei_txe_dev_init — allocates and initializes the txe hardware specific structure

like, it literally builds the txe hardware structure from scratch and gets it ready. main character energy fr fr 👑

---

🌸 SYNOPSIS 🌸

struct mei_device * mei_txe_dev_init (struct pci_dev *pdev );

so it hands you back a struct mei_device * — that's the prize, bestie 💖

---

🦋 ARGUMENTS 🦋

• pdev — the pci device. that's it, that's the argument. one (1) whole pci device, no notes ✨

---

⭐ RETURN ⭐

struct mei_device * on success, or NULL 😭

no cap, check it for NULL. if it comes back NULL, the init did not slay and you gotta handle that.
