🌸 SYNOPSIS 🌸

🫶 ARGUMENTS 🫶

• cdev — pointer to the embedded class device. that's your main character right there 👑
• attr — the device attribute. it's marked unused, so it's giving background extra energy, no lines, no screen time 💀

💅 DESCRIPTION 💅

so what does it actually do? it's a sysfs 'read-only' shost attribute. that's it, that's the whole thing. read-only means read-only bestie, do not come for her with a write ✋
