devm_of_platform_populate(9)

✨ devm_of_platform_populate(9) ✨

okay so this is a page from the Kernel API Manual, and honestly? it's a little baddie. it's called devm_of_platform_populate and no cap, it's giving "populate platform_devices from device tree data" — that's literally the NAME section, we're not skipping it 💅

---

🌸 SYNOPSIS 🌸

int devm_of_platform_populate (struct device *dev );

like, that's the whole signature. one argument. she's low maintenance. 🎀

---

🦋 ARGUMENTS 🦋

• dev — the device that requested to populate from device tree data. like, this is the one asking for the whole thing. the main character of the request, iykyk. 👑

---

💖 DESCRIPTION 💖

so bestie, here's the tea: this function is similar to of_platform_populate — same vibe, same energy — BUT with a little extra magic sprinkled on top ✨

the difference? it will automatically call of_platform_depopulate when the device is unbound from the bus. like, it cleans up after itself?? we love a self-sufficient icon. no manual teardown needed, she handles it. periodt. 🫶

🎀 RETURN 🎀

• 0 on success 🎉 — we ate, no crumbs
• < 0 on failure 😭 — it's giving flop, go check what went wrong
