...e, which now is a drm-client, can only run after drm_dev_register(). So during backlight registration the connectors are not probed yet and the drm_connector->status == connected check in nv50_backlight_init() would now always fail. Replace the drm_connector->status == connected check with a drm_helper_probe_detect() == connected check to fix nv_backlight no longer getting registered because of this.

Now that we've added the hooks that we've needed for this and used them in i915, let's add one more hook (which I could use some feedback on, I'm not sure if it's worth maybe just reworking how we do mode pruning in nouveau instead...) and start using this in our mst ->mode_valid callback to filter out impossible to set modes on MST connectors.

This is a trimmed down version of https://patchwork.freedesktop.org/series/46637/ with all of the review comments addressed. The last version of this series had fixes for the i2c and DP aux busses to ensure that the GPU would be turned on whenever anything tried to access the i2c/aux busses. Unfortunately: one of the fixes apparently contained some very incorrect usage of Linux's runtime PM

This is the latest version of https://patchwork.freedesktop.org/series/46815/ With a bunch of fixes to the new fb_helper to prevent it from breaking module loading/unloading with nouveau. Also; lots of documentation fixes and one fix in response to a kbuild bot.

This is the latest version of https://patchwork.freedesktop.org/series/46815/ I moved everything out of fb_helper and back into nouveau, because it seems that other drivers actually do have this handled already as far as I can tell.
