platform_device_add(9)

✨ platform_device_add(9) — Kernel API Manual ✨

💖 NAME 💖

okay so platform_device_add is literally the function that adds a platform device to the device hierarchy. That’s the whole vibe: putting pdev where it belongs in the device tree, bestie. 🦋

🌸 SYNOPSIS 🌸

int platform_device_add (struct platform_device *pdev );

🎀 ARGUMENTS 🎀

• pdev — the platform device we’re adding. That’s the main character here. 👑

💅 DESCRIPTION 💅

This one is part 2 of platform_device_register, periodt. But it can also be called separately — and we mean iff — like, only if — pdev was allocated by platform_device_alloc, no cap. So don’t just roll up with some random pdev and expect this to work; the allocation situation matters. 💀
