snd_hdac_ext_bus_init(9)

💅 NAME 💅

sooo this is snd_hdac_ext_bus_init — it initializes a HD-audio extended bus ✨ and yes that's the whole vibe, it's a "set the bus up" function, that's it, that's the girl

(it lives in the Kernel API Manual, iykyk 🫶)

🌸 SYNOPSIS 🌸

int snd_hdac_ext_bus_init (struct hdac_bus *bus , struct device *dev ,
       const struct hdac_bus_ops *ops , const struct hdac_ext_bus_ops *ext_ops
);

🎀 ARGUMENTS 🎀

okay bestie, here's the roster, four (4) whole parameters, no cap:

• bus — the pointer to the HDAC bus object 💖 like, the actual bus you're initializing, hand it over
• dev — device pointer 🦋 the device, being a pointer, iconic behaviour
• ops — bus verb operators ⭐ the ops for bus verbs, that's the whole description, we love a concise queen
• ext_ops — operators used for ASoC HDA codec drivers 🌈 these are the ops for the ASoC HDA codec drivers specifically, v important, don't mix them up

✨ DESCRIPTION ✨

literally all it says: returns 0 if successful, or a negative error code 😭 so like — 0 = slay, negative = something went wrong, check your vibes (and your error code) 🔥
