💅 sdca_regmap_writeable(9)

okay so bestie, welcome to the kernel API manual for sdca_regmap_writeable — yes that's the whole name, yes it's a mouthful, no we're not shortening it. this is the little bool-returning icon of ./sound/soc/sdca/sdca_regmap.c and honestly? she's giving "tiny function, big responsibility." ✨

---

🌸 NAME

sdca_regmap_writeable — return if a given SDCA Control is writeable 💅

like, that's it. that's the job. you ask her "hey is this thing writeable?" and she tells you. no cap.

---

🎀 SYNOPSIS

bool sdca_regmap_writeable (struct sdca_function_data *function ,
unsigned int reg );

literally the whole signature, copied exactly, do not come for me about the spacing 🫶

🦋 ARGUMENTS

• function — Pointer to the Function information. she needs to know which Function we're talking about, so hand her the pointer, bestie 💖
• reg — Register address/Control to be processed. this is the one getting the vibe check 👑

---

⭐ RETURN

Returns true if the register is writeable.

that's it. that's the return value. true means go off, write away. anything else means... not writeable. iconic behavior honestly 🌈
