devm_register_framebuffer(9)

💖 devm_register_framebuffer — the Kernel API Manual, bestie edition 💖

okay so this is a page from the Kernel API Manual (devm_register_framebuffer(9), yes that's the whole vibe) and it's literally about signing a framebuffer up for the devres ride 🎀

---

✨ NAME ✨

devm_register_framebuffer — resource-managed frame buffer device registration 🦋

like, it registers your framebuffer and handles the cleanup energy for you. main character behavior fr fr 💅

---

🌸 SYNOPSIS 🌸

int devm_register_framebuffer (struct device *dev , struct fb_info
*fb_info );

one function, two args, returns an int. no cap, that's the whole thing ✨

---

🎀 ARGUMENTS 🎀

• dev — the device the framebuffer belongs to 🫶 like, whose framebuffer is this? this one.
• fb_info — the frame buffer info structure 💖 the actual framebuffer lore lives in here.

---

💅 DESCRIPTION 💅

okay so picture this: you've got a frame buffer device, fb_info, and you're registering it to a device, dev. that's it, that's the function. it literally says it right there — Registers a frame buffer device fb_info to device dev. 🍓

and the return value? it returns a negative errno on error, or zero for success. zero = slay, negative = 💀. that's the vibe check, iykyk.

ngl, "resource-managed" in the NAME is the whole point of the devm_ prefix — but the page doesn't spell out extra behavior beyond what's written here, so don't come for me, i'm just reporting what the manpage says 🙈
