🦋 cdns_update_slave_status_work(9) — the Kernel API Manual era 💅

okay bestie so this one is from the Kernel API Manual and the function is cdns_update_slave_status_work — say that five times fast, i literally can't 😭 anyway it's giving kernel-internals main character energy and it's actually so good once you get it, promise 🫶

✨ NAME ✨

cdns_update_slave_status_work — update slave status in a work since we will need to handle other interrupts eg. CDNS_MCP_INT_RX_WL during the update slave process.

like, no cap, that's the whole vibe: the slave status update happens inside a work (not inline!!) because during that update you're still gonna have to deal with other interrupts, e.g. CDNS_MCP_INT_RX_WL. the way that's the entire reason this function exists?? iconic 🌸

and that's the page!! go read the others, they're right there, i literally listed them for you 🫶

quick reminder bestie: everything above is straight from the page — i didn't add any behaviour, promise, no guessing fr fr 💜

sign-off cuteness: this one lives in ./drivers/soundwire, it's dated October 2026, and the header/footer both say cdns_update..._status_work(9) — that's the manual name and the title, matching like a matching set 🎀✨💖
