DEVICE_ATTR_WO_NAMED(9)

💅 DEVICE_ATTR_WO_NAMED(9) — like, the named one ✨

okay bestie, welcome to the Kernel API Manual — yes this is a (9) page, yes it's a macro, yes we're gonna get through it together 🫶

---

✨ NAME ✨

DEVICE_ATTR_WO_NAMED — it defines a read-only device attribute, but the sysfs name is not the same as the function name. That's literally the whole personality of this macro. (And yes, the page says read-only, that's what it says, don't come for me 💀)

---

🦋 SYNOPSIS 🦋

DEVICE_ATTR_WO_NAMED (_name , _attrname );

---

🎀 ARGUMENTS 🎀

• _name — the attribute function preface. the little name-ner at the front of your function 🧚
• _attrname — the attribute name as it will be exposed in the sysfs. so like, the public-facing name, the main character name 👑

---

🌸 DESCRIPTION 🌸

So it's just like DEVICE_ATTR_WO, no cap — but here's the glow-up: it lets you reuse names under separate paths in the same driver. same name, different paths, everyone slays in their own lane ✨
