ufshcd_pltfrm_init(9)

💖 ufshcd_pltfrm_init(9) — the kernel API manual, but make it make sense 💖

okay so bestie, we're looking at ufshcd_pltfrm_init from the Kernel API Manual (section 9, the kernel-functions girlies ✨). This is the probe routine of the driver — like, the moment the driver first slides into the DMs of the hardware and goes "hi, are you there?" 🫶

🌸 NAME 🌸

ufshcd_pltfrm_init — probe routine of the driver

literally what it says on the tin, no cap: it's the driver's probe routine 💅

---

✨ SYNOPSIS ✨

int ufshcd_pltfrm_init (struct platform_device *pdev , const struct
       ufs_hba_variant_ops *vops );

two arguments, one int coming back at you. iconic signature honestly 🎀

---

🦋 ARGUMENTS 🦋

• pdev — pointer to Platform device handle. like, the actual device's little handle so the driver knows who it's talking to 🫶
• vops — pointer to variant ops. the variant-specific operations, iykyk 👑

---

💀 RETURN 💀

• 0 on success 🎉
• non-zero value on failure 😭

that's it. that's the whole vibe check. zero means slay, anything else means something went sideways.

ngl, this one's short and sweet — probe goes in, returns 0 or not. no drama, just vibes 🌸
