💖 devm_sigmadsp_init(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one lives in the sound subsystem and it's lowkey the setup babe for a SigmaDSP. let's get into it ✨

---

🌸 NAME 🌸

devm_sigmadsp_init — Initialize SigmaDSP instance

like, it literally does what it says on the tin, no cap.

---

🦋 SYNOPSIS 🦋

struct sigmadsp * devm_sigmadsp_init (struct device *dev , const struct sigmadsp_ops *ops , const char *firmware_name );

---

🎀 ARGUMENTS 🎀

• dev — the parent device 💜 like, whose child is this DSP anyway
• ops — the sigmadsp_ops to use for this instance, i.e. the whole personality of your DSP 🫶
• firmware_name — name of the firmware file to load 📂 yes bestie, we're loading a file, get into it

---

✨ DESCRIPTION ✨

So what it does: it allocates a SigmaDSP instance and loads the specified firmware file. that's the whole vibe, honestly iconic 🌈

It returns a pointer to a struct sigmadsp on success, or a PTR_ERR on error 😭 so please, please check that return value, use IS_ERR()-style brain cells, we do not raw-deref an error pointer in this house 💅

fr fr, error pointers are not real pointers, do not touch 💀
