regmap_init_sdw_mbq_cfg(9)

💖 regmap_init_sdw_mbq_cfg(9) — Kernel API Manual, but make it cute ✨

okay so bestie, we're in the regmap_init_sdw_mbq_cfg(9) girlies today, and honestly? this one's a little sleeper hit. it spins up an MBQ SoundWire register map with a config, and the device management code handles cleanup for you, which is giving main character energy if you ask me 🎀

---

✨ NAME ✨

regmap_init_sdw_mbq_cfg — Initialise MBQ SDW register map with config. literally that's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

regmap_init_sdw_mbq_cfg (dev , sdw , config , mbq_config );

---

🦋 ARGUMENTS 🦋

• dev — the struct device that will be interacted with. yes queen, this is the one doing the interacting 🫶
• sdw — the Soundwire device that will be interacted with. so many little devices getting interacted with today, we love a busy social calendar ✨
• config — Configuration for register map. the whole blueprint, the whole vibe 💅
• mbq_config — Properties for the MBQ registers. very specific, very demure 👑

---

💜 DESCRIPTION 💜

so here's the tea: the return value will be an ERR_PTR on error, or a valid pointer to a struct regmap. no cap. 🔥

and the best part? the regmap will be automatically freed by the device management code — not me having to remember to clean up, we love a self-sufficient icon 😭💖

heads up bestie: check that return value! ERR_PTR on error means you gotta use the error-checking helpers, fr fr. don't just start dereferencing and hoping for the best 🙈
