✨ acpi_node_get_parent(9) ✨

okay so bestie, buckle in, we're in the Kernel API Manual today and this little function is genuinely iconic. it's called acpi_node_get_parent and honestly? the name is a spoiler, because it does exactly what it says. no cap. 💅

🌸 NAME 🌸

acpi_node_get_parent — returns the parent fwnode of this fwnode 🫶

🎀 SYNOPSIS 🎀

struct fwnode_handle * acpi_node_get_parent (const struct fwnode_handle
*fwnode );

like, look at her. struct fwnode_handle * out front, taking one const struct fwnode_handle *fwnode as an argument. clean. no notes. 👑

💖 ARGUMENTS 💖

  • fwnode — the firmware node whose parent you're trying to get. that's it. that's the whole mood. it's giving "tell me who your mom is" energy 🧚

🦋 DESCRIPTION 🦋

so what does it actually do? it returns the parent node of an ACPI device or data firmware node. that's the whole thing. 🔥

and if there's no parent available? it returns NULL. no parent, no problem, no drama, just NULL. 🙈

like literally that's it — parent fwnode in, parent fwnode (or NULL) out. main character energy from a four-line function, we love to see it. 💜

🌈 SEE ALSO 🌈

the kernel file is ./drivers/acpi/property.c — that's where the magic lives, iykyk ✨ and here's the whole friend group, all of them showing up to the function:

fr fr if you were looking for a plot twist, there isn't one. it gets the parent. that's the post. 🫶

and that's the whole page, bestie!! 🎀 this one came out of ./drivers/acpi, dated October 2026, and honestly? slayed. periodt. 💖🌸⭐
