🌸 NAME 🌸

pm_qos_enable_show — the sysfs handler that shows you the pm qos enable value ✨ that's literally her whole job and she does it flawlessly, no cap.

🦋 SYNOPSIS 🦋

ssize_t pm_qos_enable_show (struct device *dev , struct device_attribute
*attr , char *buf );

---

🎀 ARGUMENTS 🎀

• dev — the device that's associated with the UFS controller 💖 like, that's her person, that's who she's showing up for.
• attr — the sysfs attribute handle 🌈 the lil grip she holds onto in sysfs land.
• buf — the buffer for the sysfs file 🧚 bestie this is where the answer gets written, it's the whole point.

---

💜 DESCRIPTION 💜

so what does she actually do?? she prints 1 if the PM QoS feature is enabled, and 0 if it's disabled 🎯 that's it. that's the vibe check. one digit, fully committed, zero drama 🙈

and her return value? she returns the number of characters written to buf ⭐ literally "here's how much I wrote, you're welcome."

ngl she's a tiny function but she's giving main character energy — a whole feature's on/off state, reported in a single character 💀✨
