💅 ath5k_hw_dma_stop(9) — like, the whole vibe check

okay so this is a page from the Kernel API Manual (section 9, bestie, we're in kernel-docs territory) and it's all about ath5k_hw_dma_stop 🎀

✨ NAME ✨

ath5k_hw_dma_stop — stop DMA unit 🛑✨ no cap, that's literally the whole job

---

🌸 SYNOPSIS 🌸

int ath5k_hw_dma_stop (struct ath5k_hw *ah );

---

🦋 ARGUMENTS 🦋

• ah — The struct ath5k_hw 👑 that's the one and only thing you hand it

---

💖 DESCRIPTION 💖

So what it does: it stops tx/rx DMA and interrupts 🔥 like, all of it, at once. Slay.

It returns -EBUSY if tx or rx dma failed to stop 😭 which, yeah, is the drama we don't want.

XXX: Sometimes DMA unit hangs and we have stuck frames on tx queues, only a reset can fix that. 💀 fr fr — the hint is the fix, bestie, that's it, that's the whole escape hatch.
