✨ acpiphp_check_bridge(9) ✨

Okay bestie, welcome to the acpiphp_check_bridge page from the Kernel API Manual 💅 this one is short and sweet but it's doing real work, so let's get into it.

---

🌸 NAME 🌸

acpiphp_check_bridge — re-enumerate devices

Literally what it says on the tin: it goes and re-checks all the stuff hanging off a bridge. Iconic behavior honestly 🫶

---

🦋 SYNOPSIS 🦋

void acpiphp_check_bridge (struct acpiphp_bridge *bridge );

No return value, no drama — it's a void, she does the job and leaves 👑

---

🎀 ARGUMENTS 🎀

• bridge — where to begin re-enumeration ✨ like, this is the starting point of the whole sweep. Give her the bridge and she'll take it from there.

---

💖 DESCRIPTION 💖

So here's the vibe: it iterates over all the slots under this bridge, every single one, no skipping 💅 and for each of them it makes sure of two things:

• if a card is present, the slot is enabled ✅
• if a card is not present, the slot is disabled ❌

That's the whole bit. Card there? Enable. Card gone? Disable. It's giving meticulous, it's giving thorough, fr fr 🌈

Heads up bestie: everything above is exactly what the page says — I'm not adding extra lore, so don't come for me if the bridge has opinions of its own 🙈
