[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
