rt2x00usb_r...r_multiwrite(9)

💅 rt2x00usb_register_multiwrite — from the Kernel API Manual, bestie 🎀

Okay so picture this: it's giving kernel-doc energy, it's giving driver-level realness. Let me walk you through ✨ rt2x00usb_register_multiwrite ✨ — yes that's the whole name, no we're not shortening it, it's iconic, periodt.

🌸 NAME 🌸

rt2x00usb_register_multiwrite — literally just here to write 32bit register words 💖 that's the whole job, and she does it slayfully.

---

✨ SYNOPSIS ✨

void rt2x00usb_register_multiwrite (struct rt2x00_dev *rt2x00dev , const
       unsigned int offset , const void *value , const u32 length );

No cap, that's the exact signature, don't @ me, I copied it character for character because that's how we do it here 🫶

---

🦋 ARGUMENTS 🦋

• rt2x00dev — aww look at her, the device pointer 💜 she's a struct rt2x00_dev, go look it up, the whole struct is right there.
• offset — the register offset, aka where in the register space we're hanging out 📍
• value — the actual data that should be written, like the payload, the main character of this operation 👑
• length — the length of the data. how much. the size. the amount. you get it 🌈

---

🔥 DESCRIPTION 🔥

Okay so real talk: this function is a simple wrapper 💀 like genuinely simple, don't overthink her. She exists so that 32bit register access can happen through rt2x00usb_vendor_request_buff.

That's it. That's the vibe. She's the friend who says "I know a guy" and the guy is rt2x00usb_vendor_request_buff ✨ honestly obsessed with the delegation, work smarter not harder bestie 💅

⭐ little heads-up bestie: this page comes from ./drivers/net/wireless/ralink/... and it's dated October 2026, so yeah, she's from the future, we love a time traveler 🌸

k bye, go write some 32bit register words, you're gonna do amazing 🫶💖✨
