💅 drm_edid_dup(9)

bestie, welcome to the Kernel API Manual page for drm_edid_dup(9) — yes the (9) is part of the name, it's giving kernel-section realness 👑

🌸 NAME 🌸

drm_edid_dup — duplicate a drm_edid container ✨

like, you have one and now you want two. iconic behavior honestly.

🦋 SYNOPSIS 🦋

const struct drm_edid * drm_edid_dup (const struct drm_edid *drm_edid );

🎀 ARGUMENTS 🎀

• drm_edid — the EDID to duplicate 💖 (the original, the blueprint, the main character)

💅 DESCRIPTION 💅

so here's the thing, and this is the part nobody reads but everybody should: the returned pointer must be freed using drm_edid_free. not kfree, not vibes, not "it'll sort itself out" — drm_edid_free. that's the whole description and honestly it ate 🫶

⭐ RETURN ⭐

it hands you back a drm_edid container copy 🔥 … or NULL on errors 😭 (no copy, no drama, just NULL)
