devm_hwmon_d...er_with_info(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– devm_hwmon_d...er_with_info(9) πŸ’–

okay so this is straight out of the Kernel API Manual bestie, and it's the page for devm_hwmon_device_register_with_info β€” yes the name is a whole mouthful, we're abbreviating it in the header because honestly 😭. It registers a hwmon device with info, and the "devm" part is doing so much heavy lifting here (we'll get to that). Buckle up πŸŽ€


✨ SYNOPSIS ✨

struct device * devm_hwmon_device_register_with_info (struct device *dev
, const char *name , void *drvdata , const struct hwmon_chip_info *chip
, const struct attribute_group **extra_groups );

like, five args, all on one line, absolutely unhinged formatting but we respect it πŸ’…


🌸 ARGUMENTS 🌸

  • dev β€” the parent device. the main character whose vibes this new device inherits 🫢
  • name β€” the hwmon name attribute. this is the name, and it goes on the attribute. iconic.
  • drvdata β€” driver data to attach to the created device. you're basically handing your stuff over to the new baby device 🍼
  • chip β€” pointer to hwmon chip information. the brain of the operation 🧠
  • extra_groups β€” pointer to a list of driver-specific attribute groups. your little extras, your custom flair ✨

πŸ¦‹ DESCRIPTION πŸ¦‹

It returns the pointer to the new device. that's the payoff, that's the whole thing, you get a struct device * back and you can go live your life 😌

and here's the slay part: the new device is automatically unregistered with the parent device. no manual cleanup, no "oops I forgot to unregister", no 3am debugging. devm said I got you and it meant it πŸ”₯

fr fr, this is the managed-device life β€” the unregistering just happens when the parent goes away. that's the whole point of the devm_ prefix, so don't fight it πŸ’€

πŸ‘‘ SEE ALSO πŸ‘‘

a whole friend group of register functions, one big hwmon family reunion 🌈
