✨ is_elm_present(9) ✨

okay so bestie, welcome to the Kernel API Manual — today's main character is is_elm_present, and honestly? she's serving looks and logic 💅

---

🎀 NAME 🎀

is_elm_present — checks for presence of ELM module by scanning DT nodes 🦋

like, she literally goes looking through the device tree nodes to see if the ELM module is there. iconique. no cap.

---

🌸 SYNOPSIS 🌸

bool is_elm_present (struct omap_nand_info *info , struct device_node
*elm_node );

she takes two things and she gives you back a bool — yes or no, present or not, slay or no slay 💖

---

✨ ARGUMENTS ✨

• info — NAND device structure containing platform data 🫶 like, this is the NAND device struct, and she's carrying the platform data with her, periodt.
• elm_node — ELM's DT node ⭐ this one is literally the ELM's device tree node. that's it. that's the whole vibe check.
