💅 devm_iio_backend_fwnode_get(9) ✨

okay so bestie, welcome to the kernel API manual page for devm_iio_backend_fwnode_get(9) — yes that's the whole title, yes it's a mouthful, no we're not shortening it, it's iconic and we respect it 🎀

🌸 NAME 🌸

devm_iio_backend_fwnode_get — the device-managed backend firmware node get. that's the whole vibe: managed by the device, gets you a firmware node, it's giving "responsible adult hands you the thing and cleans up after you" ✨

🦋 SYNOPSIS 🦋

struct iio_backend * devm_iio_backend_fwnode_get (struct device *dev ,
const char *name , struct fwnode_handle *fwnode );

literally just three little arguments and it hands you a struct iio_backend * back. no cap 🫶

💖 ARGUMENTS 💖

  • dev — the consumer device for the backend. like, the one that's gonna use the backend. it's the main character here 👑
  • name — the backend name. yes bestie, you gotta tell it which one 🏷️
  • fwnode — the firmware node of the backend consumer. the fwnode of the consumer, bestie, not the backend — read it twice, i did 🙈

⭐ DESCRIPTION ⭐

so what does it actually do? it gets the backend associated with a firmware node. that's it. that's the whole plot 🎬 gets you the backend, tied to your firmware node, and because it's devm_-prefixed, it's device managed — the cleanup is handled for you. lowkey the best kind of function, fr fr 💅

🔥 RETURN 🔥

  • a backend pointer 🎉 — yay, slay
  • otherwise? a negative error pointer 💀 — so like, always check it, bestie, do not rawdog this return value

🌈 SEE ALSO 🌈

the kernel file that lives here: ./drivers/iio/industrialio-backend.c

and the whole friend group, in the order the page gave them (i'm not reordering my besties):

like, that's thirty-seven entries, i counted, we do not skip, we do not summarise, we list them ALL periodt 💜

ok real talk bestie — nothing dangerous in here, but the negative error pointer thing is not a drill. check your returns before you dereference, or the kernel will humble you in front of everyone 😭

and that's the page!! ✨ sign-off time: this little beauty came out of ./drivers/iio, dated October 2026, and it's filed under devm_iio_backend_fwnode_get(9) — mwah, go read the source, ily, bye 🧚‍♀️💖
