✨ drm_class_device_unregister(9) ✨

okay so welcome to the Kernel API Manual, bestie — section 9 is where the kernel lore lives, and this page is all about drm_class_device_unregister. it's giving "cleanup era," but also "not for you unless you know what you're doing." 🫶

🌸 NAME 🌸

drm_class_device_unregister — unregister device with the DRM sysfs class. literally that's the whole gig, no cap. 💅

✨ SYNOPSIS ✨

void drm_class_device_unregister (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — device to unregister, bestie. hand over the struct device * and this function says bye to it in the DRM sysfs class. 🎀

💅 DESCRIPTION 💅

Unregisters a struct device from the DRM sysfs class. it's essentially only used by ttm to have a place for its global settings. so if you're a regular driver out here thinking "ooh, should I use this?" — no bestie, drivers should never use this. that's the rule, periodt. 🚫

lowkey important: this is not a general-purpose driver tool. the original says drivers should never use this, and we are respecting the lore. 💀
