[PATCH v2 0/4] drm/dp_mst: Add DP MST debugfs nodes for all drivers
This is the next version of my patch series for teaching DRM how to
automatically create debugfs nodes for drivers with MST topologies. This
was originally intended just for nouveau, but has since been expanded to
all DRM drivers.
Changes since previous version:
- Fix documentation error that got noticed by the kbuild bot in
"drm/dp_mst: Pass entire connector to

[PATCH] drm: serialize access to debugs_nodes.list
Nouveau, when configured with debugfs, creates debugfs files for every
channel, so structure holding list of files needs to be protected from
simultaneous changes by multiple threads.
Without this patch it's possible to hit kernel oops in
drm_debugfs_remove_files just by running a couple of xterms with
looped glxinfo.

[PATCH v2 0/5] move pstate interface to debugfs
I made a little changes in this series:
1. merge the two last patches together
2. unify the private data interface with the drm debugfs one
now it should be very obvious for a new dev on how to add new files to debugfs
and how to get access to the nouveau structs
Karol Herbst (5):
debugfs: add infrastructure to add files with other fops than only
read
debugfs: rename functions to
