drm_dev_put(9)

okay so bestie, welcome to drm_dev_put(9) from the Kernel API Manual — yes, the manual name is right there, folded in like a cute lil header note 💖.

🌸 NAME 🌸

drm_dev_put — drop reference of a DRM device. That's the name, and she's iconic.

✨ SYNOPSIS ✨

void drm_dev_put (struct drm_device *dev );

🎀 ARGUMENTS 🎀

• dev — device to drop reference of or NULL. Yep, NULL is literally listed here, no cap 🫶.

💅 DESCRIPTION 💅

This decreases the ref-count of dev by one. The device is destroyed if the ref-count drops to zero.

So like: one ref down 💅, and if that was the last one and the ref-count hits zero, the device gets destroyed. That's the whole plot, bestie — this page has no extra lore.
