💖 cdns_spi_probe(9) 💖

okay so this is a page from the Kernel API Manual — section 9, bestie, the kernel-developer section — and it's literally all about one little function: cdns_spi_probe. yes it's short. no we're not skipping anything. let's go 🫶

✨ NAME ✨

cdns_spi_probe — the probe method for the SPI driver 🌸

✨ SYNOPSIS ✨

int cdns_spi_probe (struct platform_device *pdev );

✨ ARGUMENTS ✨

• pdev — a pointer to the platform_device structure 🎀 like, that's the whole argument. one (1) pointer. iconic minimalism.

✨ DESCRIPTION ✨

so what does it actually do, you ask? it initializes the driver data structures and the hardware. both. the software vibes and the physical silicon. 💅 that's it, that's the description, and honestly it's giving "short but does the most."

✨ RETURN ✨

• 0 on success — slay ✅
• an error value on error — not slay, but at least you know 😭
