pm8001_ctl_fw_version_show(9)

🌸 pm8001_ctl_fw_version_show — it's in the Kernel API Manual, bestie ✨

okay so picture this: you're deep in pm8001_ctl.c, you need the firmware version, and this little function is literally the main character. It's a sysfs show callback — a read-only shost attribute, periodt. No writing, no drama, just vibes and a version string. 💅

✨ SYNOPSIS ✨

ssize_t pm8001_ctl_fw_version_show (struct device *cdev , struct
       device_attribute *attr , char *buf );

that's the whole signature, copy it exactly, don't @ me 🫶

---

🎀 ARGUMENTS 🎀

• cdev — pointer to embedded class device. like, the device it's attached to, iykyk 💖
• attr — device attribute, and ngl it's unused here. it's just there being decorative. icon behaviour honestly 🙈
• buf — the buffer returned. this is where the good stuff goes 🦋

---

💀 DESCRIPTION 💀

So basically: it's a sysfs 'read-only' shost attribute. That's the whole description, bestie — read-only, shost, sysfs attribute. No cap, no extra lore. 🔥

lowkey obsessed with how short this description is. minimalism ate. 👑
