platform_get_resource(9)

💅 platform_get_resource — like, the full glow-up ✨

okay bestie, pull up a chair 🎀 this one is from the Kernel API Manual, section 9, and it's genuinely one of those little functions that eats every single time. no cap.

---

🌸 NAME 🌸

platform_get_resource — get a resource for a device 💖

like, the resource. for your device. that's the whole vibe.

---

✨ SYNOPSIS ✨

struct resource * platform_get_resource (struct platform_device *dev ,
unsigned int type , unsigned int num );

look at her. iconic signature. three args, one pointer back, zero drama 🫶

---

🦋 ARGUMENTS 🦋

• dev — the platform device, aka the main character of this whole situation 👑
• type — the resource type, like which flavour of resource you're asking for
• num — the resource index, because sometimes there's more than one and you gotta be specific 💅

---

⭐ RETURN ⭐

a pointer to the resource 💖 … or NULL on failure 😭 (yes, always check. always. no skipping the vibe check.)
