get_latch_status(9)

okay so bestie, welcome to the Kernel API Manual 💅 — today's main character is get_latch_status(9), and we're getting into the latch status of a slot together. ✨

🎀 NAME 🎀

get_latch_status — get latch status of a slot

✨ SYNOPSIS ✨

int get_latch_status (struct hotplug_slot *hotplug_slot , u8 *value );

🫶 ARGUMENTS 🫶

• hotplug_slot — the slot to get status; your little hotplug slot bestie. 🦋
• value — pointer to store status. It's literally where the status goes, iykyk. 💖

🌸 DESCRIPTION 🌸

okay so here's the tea: ACPI doesn't provide any formal means to access latch status. Not a single formal way, bestie. 😭

Instead, we fake latch status from _STA. That's the whole vibe — no official latch-status hookup, so it's faked from _STA. 🎀
