11fe126625 drm/radeon/kms: reduce probe latency on digital connectors
On a system with one HDMI and one VGA connector the latter
causes output polling to run every ten seconds. This causes
full EDID re-fetch on every poll and approx. 100ms rendering
stalls are experienced by full screen page-flipping applications.
Optimisation is to trust HPD sense on R600+ ASICs and to skip
doing these expensive probes unless HPD sense has changed.

f48bb04a56 drivers/gpu/drm/radeon/radeon_cs.c: eliminate possible double free
The function radeon_cs_parser_init is only called from two places, in
drivers/gpu/drm/radeon/radeon_cs.c and drivers/gpu/drm/radeon/r600_cs.c.
In each case, if the call fails another function is called that frees all
of the kdata and dpage information in the chunks array.  So this
information should not be freed in radeon_cs_parser_init as well.

5320918b9a drm/udl: initial UDL driver (v4)
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.

2c07a21d6f drm: add core support for unplugging a device (v2)
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.

ac235dafb6 drm: Fix drm_mode_attachmode_crtc()
Change drm_mode_attachmode_crtc() to take an "all or nothing" approach.

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.
