ssam_controller_caps_load(9)

💅 NAME 💅

ssam_controller_caps_load — okay bestie, this one loads controller capabilities, and yes that's the whole vibe ✨

So real quick, we're chilling in the Kernel API Manual, section 9, and this page is literally all about one little function that goes and grabs the caps for your Surface controller 🫶

---

✨ SYNOPSIS ✨

int ssam_controller_caps_load (struct device *dev , struct
       ssam_controller_caps *caps );

That's it. That's the whole entrance. No cap 🔥

---

🎀 ARGUMENTS 🎀

• dev — a pointer to the controller device 💖 like, the device we're loading caps for, bestie, keep up.
• caps — where to store the capabilities in. Yes, that's where they go. Hand it the spot and it shall fill it 🦋

---

⭐ RETURN ⭐

Returns zero on success, and a negative error code on failure. So 0 = slay, negative = 😭💀 and you gotta go check what went wrong.
