✨ sdw_slave_rt_config ✨

okay so this is a page from the Kernel API Manual, and it's all about sdw_slave_rt_config — literally the glow-up routine for a Slave runtime handle 💅 buckle up bestie, it's short but it matters.

🎀 NAME 🎀

sdw_slave_rt_config — Configure a Slave runtime handle. that's it, that's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

int sdw_slave_rt_config (struct sdw_slave_runtime *s_rt , struct
       sdw_stream_config *stream_config );

like, it takes two things and hands you back an int. classic. 🫶

---

🦋 ARGUMENTS 🦋

• s_rt — the Slave runtime handle. your main character struct, the thing you're configuring 💖
• stream_config — the stream configuration. all the deets about how the stream should look ✨

---

💜 DESCRIPTION 💜

okay important: this function is to be called with bus_lock held. no cap, that's the whole description. not me being dramatic, that's genuinely all it says 😭 so yeah — hold the lock, then call it. periodt.
