devm_mux_state_get_selected(9)

💖 devm_mux_state_get_selected(9) 💖

okay so welcome to the Kernel API Manual, bestie — today’s main character is devm_mux_state_get_selected(9), and it’s literally the resource-managed way to get a mux-state for a device. slay. 💅

---

🌸 NAME 🌸

devm_mux_state_get_selected — get the mux-state for a device, with resource management. 🫶

---

✨ SYNOPSIS ✨

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

---

🎀 ARGUMENTS 🎀

• dev — the device that needs a mux-state. 🔥
• mux_name — the name identifying the mux-state. 🦋

---

🦋 RETURN 🦋

you get back a pointer to the mux-state, or an ERR_PTR with a negative errno. that’s the vibe: pointer = yes, ERR_PTR with negative errno = nope 😭.

---

🌈 DESCRIPTION 🌈

the returned mux-state (if valid) is already selected. periodt. 👑

and on release, the mux-state will automatically be deselected and freed — resource management is doing the cleanup arc for you, no cap. 🧚
