of_slim_get_device(9)

✨ of_slim_get_device — bestie's guide to grabbing a device from a dt node ✨

okay so this one's a kernel API page, it lives in the manual section 9 (the kernel API one, iykyk), and honestly? it's giving "small function, big responsibilities" 💅

---

🌸 NAME 🌸

of_slim_get_device — get a handle to a device using a dt node.

like, that's the whole vibe. you've got a device tree node and you want the device. slay.

---

🎀 SYNOPSIS 🎀

struct slim_device * of_slim_get_device (struct slim_controller *ctrl ,
struct device_node *np );

two args, one pointer back. classic. no cap.

---

🦋 ARGUMENTS 🦋

• ctrl — the controller on which this device will be queried. that's the Slimbus controller you're asking, bestie, like "hey do you know this one?"
• np — node pointer to device. literally just the pointer to the device_node for the device you're curious about 🫶

---

💖 DESCRIPTION 💖

so here's the tea: it takes a reference to the embedded struct device, and that reference needs to be dropped after use. not optional. not a suggestion. drop it. 🔥

bestie if you forget to drop that reference it's gonna sit there forever. don't be that person 😭

---

⭐ RETURN ⭐

pointer to a device if it has been registered, otherwise NULL.

that's it. either you get the pointer or you get NULL, and if you got NULL don't go dereferencing it, that's not a mood 💀
