regmap_init_spi(9)

✨ NAME ✨

okay so welcome to regmap_init_spi(9), straight out of the Kernel API Manual, and the name is literally regmap_init_spi — Initialise register map. no cap, that's the whole assignment bestie. 💅

🌸 SYNOPSIS 🌸

the call looks exactly like this, character for character, don't @ me:

regmap_init_spi (dev , config );

💖 ARGUMENTS 💖

• dev — device that will be interacted with 🫶
• config — configuration for register map ✨

🦋 DESCRIPTION 🦋

so the return value will be an ERR_PTR on error, or a valid pointer to a struct regmap. that's the vibe check: error path gets the ERR_PTR, success path gets the valid struct regmap pointer. iconic. 💀
