gpio_keys_attr_show_helper ✨

okay bestie, this one is straight from the Kernel API Manual, and it's giving “tiny helper, very important paperwork” energy 💅

---

🌸 NAME 🌸

gpio_keys_attr_show_helper — fill in stringified bitmap of buttons 🎀

---

🦋 SYNOPSIS 🦋

ssize_t gpio_keys_attr_show_helper (struct gpio_keys_drvdata *ddata ,
char *buf , unsigned int type , bool only_disabled );

---

💖 ARGUMENTS 💖

• ddata — pointer to drvdata. yep, that's the whole vibe 🫶
• buf — buffer where stringified bitmap is written ✨
• type — button type (EV_KEY, EV_SW) 👑
• only_disabled — does caller want only those buttons that are currently disabled or all buttons that can be disabled? that's the question bestie 🙈

---

🔥 DESCRIPTION 🔥

This function writes buttons that can be disabled to buf. if only_disabled is true, then buf contains only those buttons that are currently disabled. Returns 0 on success or negative errno on failure. no cap, that's the whole deal 💀✨
