[PATCH 2/2] drm: qxl: Remove unused debugfs code

linux
2025-04-13T17:11:09Z

qxl_debugfs_add_files() has been unused since 2022's
commit d0719e09264b ("drm/qxl: Use TTM builtin resource manager debugfs
code")

Remove it.

This now leaves the debugfs_count and debugfs members of struct
qxl_device unused. Remove them.

QXL_DEBUGFS_MAX_COMPONENTS was only used as the size of the debugfs[]
array. Remove it.
