✨ smi_spi_probe(9) ✨

okay so bestie, this is a page from the Kernel API Manual — yes, the kernel has its own manual, she's iconic like that 💅 — and today's main character is smi_spi_probe. It's a little function with a big job: spawning a whole squad of SPI devices from an array. periodt. 🦋

🌸 NAME 🌸

smi_spi_probe — instantiate multiple SPI devices from inst array

like literally, not one device, multiple. she's a multi-instantiate girlie and we love that for her 🎀

---

⭐ SYNOPSIS ⭐

int smi_spi_probe (struct platform_device *pdev , struct smi *smi ,
       const struct smi_instance *inst_array );

three args, one int back. simple synopsis, huge slay 🔥

---

💖 ARGUMENTS 💖

• pdev — the Platform device 🫶
• smi — the Internal struct for Serial multi instantiate driver 👑
• inst_array — the Array of instances to probe 🌈

ngl that's the whole roster. each one does exactly what it says on the label, no secret lore 💀

---

🧚 DESCRIPTION 🧚

so what does she return? okay bestie, listen:

it returns the number of SPI devices instantiate, or Zero if none is found, or a negative error code. 😭

that's three whole possible outcomes, so do a vibe check on your return value before you assume anything, fr fr ⭐
