xudc_probe(9)

💅 xudc_probe(9) — like, the Kernel API Manual page, bestie ✨

okay so this is the tea on xudc_probe from the Kernel API Manual — it's the device probe function for driver initialization, and honestly it's giving very "first day of school" energy 🎀

🌸 NAME

xudc_probe — the device probe function for driver initialization. that's it, that's the whole vibe 🫶

---

✨ SYNOPSIS

int xudc_probe (struct platform_device *pdev );

like, you hand it a pointer and it hands you back an int. simple. iconic. no cap 🔥

---

💖 ARGUMENTS

• pdev — pointer to the platform device structure. that's your whole main character right there 👑

---

🦋 RETURN

0 for success, and an error value on failure 😭 — so like, if it's 0 we're slaying, and if it's anything else, something went sideways fr fr.

no cap: 0 = good vibes, non-zero = the vibe check failed 💀
