💖 NAME 💖

okay so this is the Kernel API Manual page for create_of_modalias(9), and the whole point is that it Creates DT compatible string for modalias and uevent. that's it, that's the job, and it ate. ✨

✨ SYNOPSIS ✨

int create_of_modalias (const struct acpi_device *acpi_dev , char *modalias , int size );

🎀 ARGUMENTS 🎀

• acpi_dev — ACPI device object. literally the device bestie. 🫶
• modalias — Buffer to print into. 📝
• size — Size of the buffer. 📏

🌸 DESCRIPTION 🌸

so the function exposes the DT compatible modalias as of:NnameTCcompatible. 💅 that's the string format, no cap.

bestie, real talk: this function should only be called for devices having ACPI_DT_NAMESPACE_HID in their list of ACPI/PNP IDs. that's the rule. don't be out here calling it on random devices, okay? 💀
