acpi_dev_hid_uid_match(9)

💅 NAME 💅

acpi_dev_hid_uid_match — ok so this one matches a device by the HID and UID you hand it ✨

---

🎀 SYNOPSIS 🎀

acpi_dev_hid_uid_match (adev , hid2 , uid2 );

---

🌸 ARGUMENTS 🌸

• adev — the ACPI device you're trying to match. the main character of this function fr 🫶
• hid2 — the Hardware ID of the device. yep, that's the HID.
• uid2 — the Unique ID of the device. and here's the slay: pass NULL if you don't wanna check _UID at all 💅

---

🦋 DESCRIPTION 🦋

So what it does is it matches the HID and the UID inside adev against the hid2 and uid2 you gave it. iconic behaviour honestly.

And listen — the absence of uid2 gets treated as a match. like, no uid2? cool, we're not checking, you're good, no cap 🔥

Heads up bestie: if you actually do wanna validate uid2, you gotta do that before you call this function. this one is not doing it for you, periodt.

---

⭐ RETURN ⭐

• true if it matches, or if uid2 is NULL 💖
• false otherwise 💀
