Subject: [PATCH 0/5] drm/nouveau: Fix a lot of nasty RPM bugs and deadlocks

This fixes quite a number of runtime PM bugs I found that have been
causing some pretty nasty issues such as:
 - Deadlocking on boot
 - Connector probing potentially not working while the GPU is in runtime
   suspend
 - i2c char dev not working while the GPU is in runtime suspend
 - aux char dev not working while the GPU is in runtime suspend

There's definitely more parts of nouveau that need to be fixed to use
runtime power management correctly, such as the hwmon portions, but this
series just handles the more important fixes that should get into stable
for the time being.
