✨ acpi_device_fix_up_power_children(9) ✨

okay so real talk, this page comes straight out of the Kernel API Manual — the header at the top literally reads acpi_device...wer_children(9) because somebody's terminal got shy and truncated it 🙈 but bestie it's the same function, i promise. if you're here you're probably deep in ACPI power-management land, and honestly? iconic of you. 💅

🌸 NAME 🌸

acpi_device_fix_up_power_children — literally just forces a device's children into D0, no cap.

🦋 SYNOPSIS 🦋

void acpi_device_fix_up_power_children (struct acpi_device *adev );

🎀 ARGUMENTS 🎀

• adev — the parent device object, i.e. the main character 👑 whose children's power state is the thing getting fixed up. it's giving "mom rounding up the whole group chat."

💖 DESCRIPTION 💖

So here's the tea: this one calls acpi_device_fix_up_power on adev's children — but only the ones that are reported as present and enabled. that's the whole vibe check. present + enabled = you get fixed up, periodt. 🔥
