This is a port of
commit b49f184b64
Author: Ben Collins <bcollins@ubuntu.com>
from udlfb to udl kms driver.
The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the
monitor's native mode.

If we hit an error here, then we should unlock and unreference obj
before returning.

udl can only be used as an output offload so doesn't need to support
handle->fd direction.

The DRM mode config functions structure declared by drivers and pointed
to by the drm_mode_config funcs field is never modified. Make it a const
pointer.

The GEM vm operations structure is passed to the VM core that stores it
in a const field. There vm operations structures can thus be const in
DRM as well.

There should be VM_MIXEDMAP, not VM_PFNMAP, because udl_gem_fault() inserts
pages via vm_insert_page(). Other drm/gem drivers already do this.

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.
