extcon_get_extcon_dev(9)

✨ extcon_get_extcon_dev(9) ✨

okay bestie, welcome to the Kernel API Manual entry for extcon_get_extcon_dev — it's a kernel function, it lives in the extcon subsystem, and honestly? it's giving "small function, big responsibilities." 💅

---

🌸 NAME 🌸

extcon_get_extcon_dev — get the extcon device instance from the name. literally that's the whole job, and she does it slayfully 🫶

---

🦋 SYNOPSIS 🦋

struct extcon_dev * extcon_get_extcon_dev (const char *extcon_name );

---

🎀 ARGUMENTS 🎀

• extcon_name — the extcon name that you handed over when you called extcon_dev_register. yes, that exact name. no cap, that's the one it looks up 💖

---

💜 DESCRIPTION 💜

So here's the tea: if it works, you get back the pointer of the extcon device. if it doesn't work? you get ERR_PTR(err). that's it. that's the vibe check. 🔥

---

⭐ NOTE ⭐

🚨 bestie, listen to me: this function returns -EPROBE_DEFER, so it may only be called from probe functions. like, that's not a suggestion, that's the rule. calling it anywhere else is not the moment 🙈
