Currently if the DP link is lost (either because of a hot unplug, or failed link status check) we disable the DP port, but leave the rest of the pipe running. This is incompatible with the modeset disabling sequence of some platforms/configurations. At least this is the case for DP ports on the CPU as opposed to PCH. Atm we'll also get a warning when we do a modeset disable after the above link lost event, since we expect the DP port to be enabled at this point (see the bugzilla ticket for the related dmesg). Note that with this patch we'll still end up disabling the port, thanks to the HPD uevent and subsequent modeset disable. See also the next patch fixing the other half of this issue. Solution suggested by Ville.
