✨ SYNOPSIS ✨

💜 DESCRIPTION 💜

So here's the tea: this function wraps drm_gem_dma_free_object. That's literally her whole job and she does it flawlessly 💅

If you're a driver that employs the DMA helpers, then you should use this as your drm_gem_object_funcs.free handler. Like, that's the assignment. That's what she's for. Periodt 🫶
