okay so bestie, this is the drmm_kcalloc(9) page from the Kernel API Manual, and it’s literally all about a &drm_device-managed kcalloc() situation. stay with me, it’s cute 🎀

✨ NAME ✨

drmm_kcalloc — a &drm_device managed kcalloc() 🦋

🌸 SYNOPSIS 🌸

void * drmm_kcalloc (struct drm_device *dev , size_t n , size_t size ,
       gfp_t flags );

🦋 ARGUMENTS 🦋

• dev — DRM device 💖
• n — number of array elements to allocate
• size — size of array member
• flags — GFP allocation flags

🔥 DESCRIPTION 🔥

okay so drmm_kcalloc is the drm_device-managed version of kcalloc. the allocated memory is automatically freed on the final drm_dev_put, and it works exactly like a memory allocation obtained by drmm_kmalloc. no cap, that’s the whole vibe 💅
