[PATCH 8/9] drm/qxl: remove unused debugfs structure

From: Maíra Canal
Date: Mon Dec 26 2022 - 10:53:57 EST


The current debugfs structure was introduced at f64122c1f6ad and it was
never used by the driver. Considering the addition of more
device-centered functions to the DRM core, remove the current debugfs
structure.
