✨ NAME ✨

drm_panel_add — add a panel to the global registry. that's it, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

void drm_panel_add (struct drm_panel *panel );

not me giving you the exact signature, character for character, because we do NOT freestyle function signatures in this house 😤

---

🌸 ARGUMENTS 🌸

• panel — the panel to add 🫶. that's your struct drm_panel * right there, the main character of this whole function.

---

👑 DESCRIPTION 👑

okay so what does it do? it adds a panel to the global registry so that display drivers can look it up later. it's giving "putting your name on the list so the bouncer knows you" 🌈✨

but — and this is the important part, so pay attention — the panel you're adding must have been allocated by devm_drm_panel_alloc. fr fr. that's a hard requirement, not a suggestion 💀 don't come at this function with some random panel you allocated yourself, it will not slay.

🚨 reminder: panel allocated by devm_drm_panel_alloc = yes. anything else = no. periodt.
