Kernel API Manual energy, bestie — this is the page for acpi_mipi_scan_crs_csi2, and we are keeping every fact exactly where it belongs. No cap. ✨

🌸 NAME 🌸

acpi_mipi_scan_crs_csi2 — Create ACPI _CRS CSI-2 software nodes. That's the whole name section, short and iconic. 💅

💖 SYNOPSIS 💖

void acpi_mipi_scan_crs_csi2 (void );

🎀 ARGUMENTS 🎀

• void — no arguments. Not one. Zero. The function is out here with main character energy and nothing to pass in. 🫶

🔥 DESCRIPTION 🔥

okay so before you call her, listen: this function must be called before any struct acpi_device objects are bound to any ACPI drivers or scan handlers. Periodt. Because of that, it cannot assume the existence of struct acpi_device objects for every device present in the ACPI namespace. Like, they might not be there yet — do not come for her with assumptions. 😭💀

Also, acpi_scan_lock in scan.c must be held when calling this function. Not optional, not a suggestion, not a maybe. Hold the lock, bestie. 🔒💖
