[PATCH 00/19] drm: debugfs: Remove all files automatically on cleanup

[Noralf Trønnes]

This patchset removes the need for drivers to clean up their debugfs
files on exit. It is done automatically in drm_debugfs_cleanup().
This funtion is also called should the driver error out in it's
drm_driver.debugfs_init callback.

Two drivers still use drm_debugfs_remove_files():
- tegra in it's connectors, not sure if I can remove it.
- qxl because it's debugfs files list is part of struct qxl_device which
  is freed on unload before drm_minor_unregister() is called cleaning debugfs.

Daniel,
I was unable to remove the drm_driver.debugfs_cleanup hook completely,
since drm/msm uses it to free memory. Maybe it can be freed elsewhere.


Note:
The driver patches are only compile tested.


Noralf.
