devm_reset_...ive_by_index(9)

📦 version 7.3.1, in nixpkgs unstable

💅 devm_reset_control_get_exclusive_by_index — from the Kernel API Manual, bestie

okay so first things first, the function's full name is devm_reset_control_get_exclusive_by_index, but the header shortens it to devm_reset_...ive_by_index(9) because manpage titles have a character limit and honestly same, we've all been there 🫶

✨ NAME ✨

devm_reset_control_get_exclusive_by_index — it's the resource managed version of reset_control_get_exclusive(), and yes that's the whole personality 💖

🌸 SYNOPSIS 🌸

struct reset_control * devm_reset_control_get_exclusive_by_index (struct
device *dev , int index );

no cap, that's literally the whole call ✨

🎀 ARGUMENTS 🎀

  • dev — the device that's gonna get reset by the controller. it's the main character here 👑
  • index — the index of the reset controller. which one are we talking about? this number. 🔢

🦋 DESCRIPTION 🦋

so this is the managed reset_control_get_exclusive. and "managed" is the key word, bestie — for reset controllers returned from this function, reset_control_put gets called automatically on driver detach. like, the kernel handles the cleanup for you. no manual put, no leaks, no stress. it's giving responsible adult energy 💅✨

if you want the full lore, see reset_control_get_exclusive for more information 🫶
