✨ NAME ✨

amd_halo_wmi_set_rgb — Set all RGB channels atomically 💅

like, all three at once, in one go, no half-lit chaos. iconic behavior tbh 🎀

🌸 SYNOPSIS 🌸

int amd_halo_wmi_set_rgb (struct wmi_device *wdev , u32 r , u32 g , u32 b );

🦋 ARGUMENTS 🦋

• wdev — WMI device pointer. this is the lil handle to the device you're talking to, your main character 🫶
• r — brightness for red channel (0 - 100) 🔥
• g — brightness for green channel (0 - 100) 🍓
• b — brightness for blue channel (0 - 100) 💜

so real talk — each channel is a brightness value from 0 to 100, no cap. that's the range. that's the vibe check.

⭐ RETURN ⭐

0 on success, negative error code on failure 😭

like… zero means slay, negative means something went off and you should lowkey check it. periodt.
