sdw_ml_sync_bank_switch(9)

💅 sdw_ml_sync_bank_switch(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual and it's about sdw_ml_sync_bank_switch — the whole Multilink register bank switch moment. it's short, it's sweet, it's giving "small function, big responsibilities" energy. let's get into it 🫶

---

✨ NAME ✨

sdw_ml_sync_bank_switch — Multilink register bank switch. that's it. that's the vibe. no cap. 🎀

---

🌸 SYNOPSIS 🌸

int sdw_ml_sync_bank_switch (struct sdw_bus *bus , bool multi_link );

like yes, she takes two things and hands you back an int. iconic behavior honestly 💅

---

🦋 ARGUMENTS 🦋

• bus — your SDW bus instance. the main character of this whole operation tbh 👑
• multi_link — a bool telling you whether this is a multi-link stream with hardware-based sync. so like, is this the hardware-sync multi-link situation or nah? that's the whole question 🧚

---

💖 DESCRIPTION 💖

so here's the tea, bestie: the caller function should free the buffers on error.

⚠️ ok but seriously — that's not a suggestion, that's the contract. if this thing comes back with an error, you are on buffer cleanup duty. nobody's gonna do it for you. not to be dramatic but 😭💀 — free the buffers. periodt.
