It's deprecated and only should be used by drivers which still use

is called indirectly through drm_mode_config_cleanup, which calls into
crtc->destroy, which already has the call to drm_crtc_cleanup. Which

totally runs counter to where we want to go with libdrm device
handling. The function looks in the device hierarchy for whether
controlD* exist using the following format string:
The "/drm" subdirectory is the glue directory from the sysfs class
stuff, and the only way to get at it seems to through
kdev->kobj.parent (when kdev is represents e.g. the card0 chardev
instance in sysfs). Git grep says we're not the only ones touching
that, so I hope it's ok we dig into such internals - I couldn't find a
proper interface for getting at the glue directory.
Quick git grep shows that at least -amdgpu, -ati are using this.
-modesetting do not, and on -intel it's only about the 4th fallback
path for device lookup, which is why this didn't blow up earlier.
Oh well, we need to keep it working, and the simplest way is to add a
symlink at the right place in sysfs from controlD* to card*.

drm/amd/powerplay: use pr_debug to print function not implemented message
For CZ, some function pointers like display_configuration_changed
are not set. So when HW manager tries to configure display, we
end up with messages like
"[ powerplay ] this function not implement!"
in the logs. This message is informational, but lacks details
on which function is not implemented and why.
Rather than using KERN_INFO to print the message everytime the
system boots, we rather use pr_debug so that it is only printed
when debug prints are enabled at runtime.

When DPMS was introduced to atomic, vblanks only worked when the crtc

crtc_state->active, which may cause an attempt for vblank_get to fail.
This is probably harmless, but convert from enable to active anyway.
