of_drm_find_and_get_bridge(9)

💅 of_drm_find_and_get_bridge(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ we're literally in of_drm_find_and_get_bridge(9) territory and it's giving "small function, big responsibilities" energy. stay with me, this one's short and slay.

---

🌸 NAME 🌸

of_drm_find_and_get_bridge — find the bridge that matches a device node in the global bridge list 🫶

✨ SYNOPSIS ✨

struct drm_bridge * of_drm_find_and_get_bridge (struct device_node *np );

🎀 ARGUMENTS 🎀

• np — device node. that's it, that's the whole input. it's the thing you're matching against 💖

🦋 DESCRIPTION 🦋

so here's the tea: the refcount of the returned bridge is incremented. like, it comes back with a little extra baggage and you own it now.

⚠️ bestie listen — use drm_bridge_put when you're done with it. don't just ghost it, that's a leak and the kernel will NOT be cute about it 😭

⭐ RETURN ⭐

• drm_bridge control struct on success 🔥
• NULL on failure 💀
