💅 fsldma_run_tx_complete_actions — cleanup a single link descriptor

okay so this is from the Kernel API Manual, bestie — yes, the actual kernel docs, we're literally in the big leagues today 🎀

---

✨ SYNOPSIS ✨

dma_cookie_t fsldma_run_tx_complete_actions (struct fsldma_chan *chan ,
       struct fsl_desc_sw *desc , dma_cookie_t cookie );

like, that's the whole signature, no cap 💖

---

🫶 ARGUMENTS 🫶

• chan — the Freescale DMA channel. your channel. your main character 🦋
• desc — the descriptor to cleanup and free. she's done her job, now she gets released 😭
• cookie — the Freescale DMA transaction identifier. yes it's really called a cookie 🍓

---

🌸 DESCRIPTION 🌸

so the vibe here is: this function gets called on a descriptor that's already been executed by the DMA controller. it's the little post-run ritual ✨

what it does, fr fr:

• runs any callbacks that got attached
• submits any dependencies

that's it, that's the function — she cleans up a single link descriptor and moves on 💅 periodt.
