π devm_hwmon_d...er_with_info(9) π
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 π. 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 π
β¨ SYNOPSIS β¨
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 π
πΈ ARGUMENTS πΈ
devβ the parent device. the main character whose vibes this new device inherits π«Άnameβ the hwmon name attribute. this is the name, and it goes on the attribute. iconic.drvdataβ driver data to attach to the created device. you're basically handing your stuff over to the new baby device πΌchipβ pointer to hwmon chip information. the brain of the operation π§extra_groupsβ pointer to a list of driver-specific attribute groups. your little extras, your custom flair β¨
π¦ DESCRIPTION π¦
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 π
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 π₯
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 π
