💅 __drm_gem_destroy_shadow_plane_state — NAME ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's called __drm_gem_destroy_shadow_plane_state, and it literally cleans up shadow-buffered plane state. that's the whole vibe. she's a cleanup girlie 🧹💖

🌸 SYNOPSIS 🌸

void __drm_gem_destroy_shadow_plane_state (struct drm_shadow_plane_state
*shadow_plane_state );

like, she takes one thing and returns nothing (void, no cap) 🫶

🦋 ARGUMENTS 🦋

• shadow_plane_state — the shadow-buffered plane state 💫 that's it, that's the argument. she's the plane state that's shadow-buffered, and she's the one getting cleaned up.

⭐ DESCRIPTION ⭐

So here's the tea ☕: this function cleans up shadow-buffered plane state. cleanup era, honestly 👑

And the reason she exists as a lil' __-prefixed helper is that she's helpful for drivers that subclass struct drm_shadow_plane_state — like, if your driver is doing the subclass thing and needs the inner cleanup without the whole wrapper situation, this is your girl. iykyk 💅

ngl the subclassing detail is the whole point of this function — don't skip it 🫶
