There are also two fixes:
- In DRAW_INDEX_2, we read idx_value, but should have read idx+1.
- When correcting SQ_VTX_CONSTANT_WORD1_0.SIZE, we should subtract
the offset.

In order to satisfy all the various Kconfig options between
USB and DRM, we need to split the USB code out into a separate module
and export symbols to it.
This fixes build problems in -next reported by sfr.

This is an initial drm/kms driver for the displaylink devices.
Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.
On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.
This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.

Two parts to this, one is simple unplug from sysfs for the device node.
The second adds an unplugged state, if we have device opens, we
just set the unplugged state and return, if we have no device
opens we drop the drm device.
If after a lastclose we discover we are unplugged we then
drop the drm device.
v2: use an atomic for unplugged and wrap it for users,
add checks on open + mmap + ioctl entry points.

In order to get correct ordering at hot-unplug for userspace,
we need to tear down all the sysfs bits at the correct time.
This adds a helper to allow drivers to remove the sysfs nodes
for all connectors.

The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.
The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.
To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

Change drm_mode_attachmode_crtc() to take an "all or nothing" approach.
If an error is returned, there are no side effects visible.
Also change the function to always duplicate the mode passed in.
Also change the function to not give up when it finds the first
connector without and encoder.
A simpler approach would be to just remove the function completely as
it's unused currently.

NVIDIA appear to do these around the same place they do the MODE_CTRL
