DEVICE_ATTR_RW(9)

💖 NAME 💖

DEVICE_ATTR_RW — Define a read-write device attribute. Periodt 💅✨

✨ SYNOPSIS ✨

DEVICE_ATTR_RW (_name );

🎀 ARGUMENTS 🎀

• _name — Attribute name. That’s the name-name, bestie — it’s literally doing exactly what it says on the label 🏷️🫶

🦋 DESCRIPTION 🦋

Okay so it’s giving DEVICE_ATTR, but with the values already slotted in: Like DEVICE_ATTR, but _mode is 0644, _show is <_name>_show, and _store is <_name>_store. No cap, that’s the whole vibe 🔥
