This patchset restores regressed SOR driver probing on Nyan Chromebook.

Changelog:

v2: - Changed host1x and Tegra DRM drivers such that DRM device is
      registered early now. This removes the need to change DRM core.

    - Introduced dev_err_probe() patch again. Previously Thierry rejected
      it, saying that he likes his variant more, but I kept that patch in
      grate kernel and it happened to be very handy to have because I
      instantly identified the problem in the DP AUX driver with it,
      which would've been much more difficult to do otherwise.
      Please apply it this time.

Dmitry Osipenko (4):
  gpu/host1x: Add init/deinit callbacks to host1x driver framework
  drm/tegra: Create DRM device early
  drm/tegra: dpaux: Restore DP AUX DDC registration order
  drm/tegra: Use dev_err_probe()
