✨ devm_drm_panel_add(9) ✨

okay bestie, so this is a page from the Kernel API Manual (the devm_drm_panel_add one, yes the whole page is named after the function, iconic behavior honestly 💅) and it's literally just about registering your panel the managed way. Let's get into it 🫶

---

🌸 NAME 🌸

devm_drm_panel_add — add a panel to the global registry using devres

---

🎀 SYNOPSIS 🎀

int devm_drm_panel_add (struct device *dev , struct drm_panel *panel );

---

🦋 ARGUMENTS 🦋

• dev — the device to which the panel is attached
• panel — the panel to add

---

✨ DESCRIPTION ✨

So what we're doing here is adding a panel to the global registry so that display drivers can look it up later. Simple enough, right? 💖

But listen — the panel you're adding must have been allocated by devm_drm_panel_alloc. That's not optional, that's the whole vibe check. No cap.

And here's the slay part: unlike drm_panel_add, with this function there is no need to call drm_panel_remove — it just gets called automatically for you. That's the devres magic, bestie. You literally don't have to lift a finger. Main character energy fr fr 🔥

💀 reminder: the devm_ prefix is doing the cleanup work for you, so don't go manually removing what devres already handles. periodt.
