thc_dev_init(9)

💅 thc_dev_init(9) — like, the whole glow-up ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this is the page for thc_dev_init(9), and honestly it's giving "main character origin story" because literally everything else on this page depends on this one working first. no pressure or anything 💀

---

✨ NAME ✨

thc_dev_init — allocate and initialize the THC device structure 💖 (yes, both. she does it all.)

---

🌸 SYNOPSIS 🌸

struct thc_device * thc_dev_init (struct device *device , void __iomem
*mem_addr );

like, that's the whole signature. two args in, one pointer out 🫶

---

🦋 ARGUMENTS 🦋

• device — the pointer of device structure. yep, that's the struct, hand her the pointer and off she goes ✨
• mem_addr — the pointer of MMIO memory address. this one's the void __iomem *, so it's lowkey special — memory-mapped I/O energy 💅

---

🔥 RETURN 🔥

• 👑 the thc_device pointer on success
• 😭 NULL on failed

that's it. that's the vibe check. if you get NULL back, she did not slay, and you should probably not keep going.

so yeah 🧚 that's the page. footer says October 2026 and the source line is ./drivers/hid/intel-thc-hid/in... (truncated in the original, not me being lazy, I promise 🙈). going out with a thc_dev_init(9) flourish — mwah 💜
