devm_regmap_init_sdw(9)

💖 devm_regmap_init_sdw(9) 💖

okay bestie, this is a page from the Kernel API Manual, and it's literally all about one little function that sets you up with a managed register map over SoundWire. lowkey iconic, highkey useful. let's get into it 🫶

---

✨ NAME ✨

devm_regmap_init_sdw — initialise a managed register map. that's it, that's the vibe 🎀

---

🌸 SYNOPSIS 🌸

devm_regmap_init_sdw (sdw , config );

like, that's the whole call. two arguments, no drama 💅

---

🦋 ARGUMENTS 🦋

• sdw — the device you're gonna be interacting with, bestie. that's your main character right there 👑
• config — the configuration for the register map. yes, you gotta hand over the settings, no cap 🌈

---

💜 DESCRIPTION 💜

so here's the tea: the return value will be an ERR_PTR on error, or a valid pointer to a struct regmap if everything slays. 🔥

and the best part? the regmap gets automatically freed by the device management code. not me having to manually clean up — we love a self-cleaning situation, fr fr ✨🧚

no cap: it's managed, so the device management code handles the freeing for you. periodt.
