David Herrmann dutifully moved this locking along when moving the
agp_init call out of the generic drm_dev_register into the pci
specific load helpers.
But afaict there's no need and the reason for that locking has been
purely a historical accident - we need the lock around the driver dev
node registration to paper over the midlayer init races, and the agp
init simply ended up in there. The real fix for all this is of course
to delay the dev (and sysfs/debugfs) interface registration until
everything is fully set up.
Until then stop the cargo-cult locking from spreading and remove the
locking.

Call drm_pci_agp_destroy directly, there's no point in the
indirection. Long term we want to shuffle this into each driver's
unload logic, but that needs cleared-up drm lifetime rules first.
v2: Add a dummy function for !CONFIG_PCI, spotted my David Herrmann.
v3: Fixup for the coding style police.

Wrapping a kfree is pointless.
v2: Add a comment to the kerneldoc for drm_agp_init to explain where
the kfree happens as requested by David. Note that for modeset drivers
agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop
and drivers must call drm_agp_release on their own. Which they all
seem to do properly.

The PCI bus helper is the only user of it. Call it directly before
device-registration to get rid of the callback.
Note that all drm_agp_*() calls are locked with the drm-global-mutex so we
need to explicitly lock it during initialization. It's not really clear
why it's needed, but lets be safe.
v2: Rebase on top of the agp_init interface change.
v3: Remove the rebase-fail where I've accidentally killed the ->irq_by_busid
callback a bit too early.

Only the two intel drivers need this and they can easily check for

imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which
leaves the CRTC attached to the DRM device. Also, it does setup after
attaching the CRTC to the DRM device.
Fix this by reordering the function such that we do the setup before
drm_crtc_init(): this fixes both issues.

Enable lock claims that it is serializing tve_enable/disable calls.
However, DRM already serialises mode sets with a mutex, which prevents
encoder/connector functions being called concurrently. Secondly,
holding a spinlock while calling clk_prepare_enable() is wrong; it
will cause a might_sleep() warning should that debugging be enabled.
So, let's just get rid of the enable_lock.

There's really no need for the drm core to keep a list of all
devices of a given driver - the linux device model keeps perfect
track of this already for us.
The exception is old legacy ums drivers using pci shadow attaching.
So rename the lists to make the use case clearer and rip out everything
else.
v2: Rebase on top of David Herrmann's drm device register changes.
Also drop the bogus dev_set_drvdata for platform drivers that somehow
crept into the original version - drivers really should be in full
control of that field.
v3: Initialize driver->legacy_dev_list outside of the loop, spotted by
David Herrmann.
v4: Rebase on top of the newly created host1x drm_bus for tegra.

There's no reason to keep a reference to objects in the name idr. Each
handle to an object has a reference to the object and just before we
destroy the last handle we take the object out of the name idr. Thus,
if an object is in the name idr, there's at least one reference to the
object.
Or to put it another way, the name idr reference will never keep the
object alive. It just looks like it, which is confusing.

Sometimes we want to disable all the screens on a system, because that
will allow the graphics card to be put into low-power states. The
problem is that, for example, while all screens are disabled, if we
get a hotplug interrupt, fbcon will decide to set a mode instead of
keeping everything disabled, which will remove us from our low power
states.
Let's assume that if there's a DRM master, it will be able to do
whatever is appropriate when we get the hotplug.
This problem can be reproduced by the runtime PM test program from
intel-gpu-tools: we disable all the screens so the graphics device can
be put into D3, then something triggers a hotplug interrupt, fbcon
sets a mode and breaks our test suite. The problem can be reproduced
more easily by the "i2c" subtest.
Other approaches considered for the problem:
- Return "false" if "bound == 0" and the caller of
drm_fb_helper_is_bound is a hotplug handler. This would break
the case where the machine boots with no outputs connected, then
the user plugs a monitor.
- Add a new IOCTL to force fbcon to not set modes. This would keep
all the current applications behaving the same, but adding a new
IOCTL is not always the greatest idea.
- Return false only if "dev->primary->master && bound == 0". This
was my first implementation, but Chris suggested we should do
the check irrespective of the "bound" variable.
Thanks to Daniel Vetter for the investigation, ideas and the
implementation of the hotplug alternative.
v2: - Do the check first, irrespective of "bound".

Steven Rostedt and Arnaldo Carvalho de Melo reported a panic

This problem will occur when we do:
echo nfnetlink_log > /proc/sys/net/netfilter/nf_log/any_file
rmmod nfnetlink_log
and then access the files.
Since the nf_loggers of netns hasn't been unset, it will point
to the memory that has been freed.
