devm_regmap_init_w1(9)

💖 NAME 💖

okay so bestie, this is devm_regmap_init_w1(9) straight outta the Kernel API Manual, and it is literally here to Initialise managed register map 💅✨

🌸 SYNOPSIS 🌸

devm_regmap_init_w1 (w1_dev , config );

🎀 ARGUMENTS 🎀

• w1_dev — the device that will be interacted with, bestie 🫶
• config — configuration for register map 🎀

✨ DESCRIPTION ✨

the way this works is: the return value will be an ERR_PTR on error, or a valid pointer to a struct regmap 👑 so like, error vibe check = ERR_PTR, success vibe check = valid struct regmap pointer.

and the best part? the regmap will be automatically freed by the device management code 🌸 managed regmap energy fr fr, no cap.
