cs_dsp_mock_regmap_init(9)

💅 cs_dsp_mock_regmap_init(9) — like, the Kernel API Manual one, bestie

okay so picture this: you're in the kernel, you need a regmap that isn't real, and you need it to exist. that's this function. it's from the Kernel API Manual, and ngl it's a whole little icon. let's get into it 🎀

---

✨ NAME ✨

cs_dsp_mock_regmap_init — literally just: initialize a mock regmap. she does exactly what it says on the tin, no cap 🫶

---

🌸 SYNOPSIS 🌸

int cs_dsp_mock_regmap_init (struct cs_dsp_test *priv );

---

🦋 ARGUMENTS 🦋

• priv — pointer to a struct cs_dsp_test object, bestie. and listen, this isn't optional-vibes: it must have a valid pointer to a struct cs_dsp in which the type and rev fields are set to the type of DSP you wanna simulate. like, set those fields. do it. 💅

---

👑 DESCRIPTION 👑

so on success, the priv->dsp->regmap will point to the created regmap instance. that's it, that's the whole glow-up — the mock regmap now exists and your dsp struct knows where it lives ✨

---

🔥 RETURN 🔥

zero on success, else a negative error code 😭 (so like, check it. please. for me.)

🧚 real talk: get that struct cs_dsp pointer valid and those type and rev fields set before you call this, or the whole vibe check fails. mwah 💖
