devm_iio_backend_get(9)

📦 version 7.3.1, in nixpkgs unstable

💖 devm_iio_backend_get 💖

okay so this is a page straight out of the Kernel API Manual (yes bestie, the kernel has lore and it's giving extremely official) and it's all about grabbing a backend device the device-managed way. no cap, it's a short one, but it ate. ✨

🌸 NAME 🌸

devm_iio_backend_get — Device managed backend device get 🎀

like, it gets you a backend device, and it's device managed. the vibes are immaculate and the cleanup is automatic. iykyk.

🦋 SYNOPSIS 🦋

struct iio_backend * devm_iio_backend_get (struct device *dev , const
char *name );

that's the whole signature, character for character, don't come for me 💅

🎀 ARGUMENTS 🎀

  • dev — the consumer device for the backend. like, who's asking for the backend, bestie? this one. 🫶
  • name — the backend name. literally just the name of the backend. iconic.

💅 DESCRIPTION 💅

Gets the backend associated with dev.

that's it. that's the description. short and slay. it's giving "main character energy with one line of dialogue." no need to overthink it, the function does what it says on the tin: you hand it a device, it hands you back the backend that's associated with it. 💜

🔥 RETURN 🔥

A backend pointer on success — and a negative error pointer otherwise. so if things go sideways, you're getting a negative error pointer, not a NULL, so check it with IS_ERR(), okay? 😭 don't skip the vibe check on the return value, fr fr.

🌈 SEE ALSO 🌈

okay this list is long and i'm obsessed, here's the whole squad, nobody left behind:

Kernel file ./drivers/iio/industrialio-backend.c

💖 reminder bestie: the return value can be a negative error pointer, so always run that vibe check with IS_ERR() before you dereference anything. protect your kernel, protect your peace. 🧚

and that's the whole page, no notes. this little beauty lives over in ./drivers/iio and the manual was stamped October 2026 — so go forth, get your backend, and slay 💅✨👑
