devm_mux_sta...nal_selected(9)

💅 devm_mux_sta...nal_selected(9)

okay so this is a page from the Kernel API Manual (the 9 section, the kernel-doc girlies know) and honestly? it's a little baddie. let's get into it 💖

---

✨ NAME ✨

devm_mux_state_get_optional_selected — grab the optional mux-state for a device, but like… with resource management. devm-coded. no cap.

---

🦋 SYNOPSIS 🦋

struct mux_state * devm_mux_state_get_optional_selected (struct device
*dev , const char *mux_name );

that's the whole vibe. one function, two args, slays. ✨

---

🎀 ARGUMENTS 🎀

• dev — the device that's out here needing a mux-state. it's giving "please give me a mux-state, i'm literally a device."
• mux_name — the name that identifies the mux-state. it's the ✨identifying✨ name. yes that's the whole description, it's a short king. 👑

---

🔥 RETURN 🔥

so here's the vibe check on what you get back:

• a pointer to the mux-state on success 🎉
• an ERR_PTR with a negative errno on error 😭
• NULL if the mux doesn't exist — she's not here, she's not coming 💀

---

🌸 DESCRIPTION 🌸

the returned mux-state (if valid) is already selected. no extra steps bestie, it's pre-selected for you. main character energy only.

and the best part?? the mux-state will automatically be deselected and freed on release. devm said "i'll handle it" and she DID. 🫶 no manual cleanup, no leaks, no stressed vibes.

reminder bestie: this is kernel API, so keep those names and signatures exactly as they are. no renaming, no "improving", no inventing extra behavior. the vibes are mine, the facts are not. 🙈
