✨ NAME ✨

snd_ac97_reset — Reset AC'97 device 🎀

---

🌸 SYNOPSIS 🌸

int snd_ac97_reset (struct snd_ac97 *ac97 , bool try_warm , unsigned int
id , unsigned int id_mask );

like, that's the whole vibe. four args, one int coming back. slay.

---

🦋 ARGUMENTS 🦋

• ac97 — The AC'97 device to reset. this is the main character of the whole function, the thing getting the glow-up (reset).
• try_warm — Try a warm reset first. lowkey the "let's be gentle first" flag 🫶
• id — Expected device vendor ID. the vibe check the device has to pass.
• id_mask — Mask that is applied to the device ID before comparing to id. this is the filter, iykyk.

---

💅 DESCRIPTION 💅

This function resets the AC'97 device. periodt.

If try_warm is true, the function first performs a warm reset 🔥 (nice and cosy, no cold water).

If try_warm is false, the function issues cold reset followed by a warm reset 💀 (full cold plunge and then the warm one — no skipping steps, bestie).

If id is 0, any valid device ID will be accepted 🌈 — she's not picky, she's accepting applications from all valid IDs. Otherwise, only the ID that matches id and id_mask is accepted 👑. literally only the one that fits the mask, no exceptions, no cap.

---

⭐ RETURN ⭐

• 1 — if warm reset is successful 🎉
• 0 — if cold reset and warm reset are successful 😌 (both of them, ate and left no crumbs)
• -ENODEV — if id and id_mask not matching 😭 the device did NOT pass the vibe check
