💖 ish_dev_init(9) — Kernel API Manual 💖

okay bestie, welcome to ish_dev_init(9), straight out of the Kernel API Manual. yes the original literally spells it "Initialize ISH devoce" and honestly? iconic typo, we're keeping the vibe, it means device. no cap. 🫶

---

✨ NAME ✨

ish_dev_init — initialize the ISH devoce (device, bestie, it's device 💅)

---

🌸 SYNOPSIS 🌸

struct ishtp_device * ish_dev_init (struct pci_dev *pdev );

like, that's the whole summoning ritual right there ⭐

---

🎀 ARGUMENTS 🎀

• pdev — the PCI device. that's your little card, your guy, your main character. you hand it over and the function does its thing with it 🦋

---

💫 DESCRIPTION 💫

so what does it actually do? two things, and they're both important:

• it allocates an ISHTP device ✨
• and it initializes IPC processing 💜

that's it. that's the whole function. lowkey elegant, highkey essential. iykyk.

---

🔥 RETURN 🔥

on success you get the ISHTP device instance back — your brand new baby 👑

otherwise? NULL. literally nothing. the void. 😭
