acpiphp_unre...er_attention(9)

💅 NAME 💅

ok so this page is about acpiphp_unregister_attention — which is literally the "unset attention LED callback" girlie. that's the whole job. she takes the callback away. periodt. ✨

this one lives in the Kernel API Manual, and honestly she's a short read but she matters, so let's go 🫶

---

✨ SYNOPSIS ✨

int acpiphp_unregister_attention(struct acpiphp_attention_info *info);

like yes bestie, that's the whole signature. int return, one pointer argument, no cap 💅

---

🎀 ARGUMENTS 🎀

• info — this one's gotta match the pointer you used to register. not "a" pointer, not "a similar" pointer — the pointer. same energy or it doesn't count 🙈

---

🌸 DESCRIPTION 🌸

okay so here's the vibe 🦋 — this function is used to un-register a hardware specific acpi driver that manipulates the attention LED. that's it, that's the gig.

and like, the important part, the part where you gotta pay attention (pun intended 😭): the pointer to the info struct must be the same as the one used to set it. the way that this is non-negotiable. no sneaky new structs, no "close enough" — same pointer or nothing 💀

think of it as the breakup text that only works if you're texting the exact same person you were dating. yikes but true.

quick vibe check: ./drivers/pci/hotplug is where she hangs out, the page is dated October 2026, and the manual name on the tin is acpiphp_unre...er_attention(9) — yeah the header got truncated, she's mysterious like that 💅

okay that's the whole page, you ate that, go unregister some attention LEDs bestie 🎀🔥👑
