✨ SYNOPSIS

DRM_DEV_DEBUG_DRIVER (dev , fmt , ... );

yes that's the whole vibe, no cap 💅

🫶 ARGUMENTS

• dev — the device pointer, literally the thing you're talking about 🔥
• fmt — a printf like format string, so you know how this goes: you bring the template, it brings the magic ✨
• ... — variable arguments, the lil extras that get slotted into your fmt 🍓

💀 NOTE

this is deprecated in favor of drm_dbg or dev_dbg. not me telling you this is the old way 😭 please use drm_dbg or dev_dbg instead — that's the main character energy now 👑
