[PATCH 0/9] Fix runtime pm ref leaks
In preparation for runtime pm on muxed dual GPU laptops,
I've fixed all runtime pm ref leaks I could find in nouveau,
radeon and amdgpu.
To ease reviewing, I've pushed this series to GitHub:
https://github.com/l1k/linux/commits/drm_runpm_fixes_v1
@Alex Deucher: I do not have an AMD GPU so couldn't test this
beyond verifying that it compiles. Please double-check the patches
and test

[PATCH v2 00/15] Runtime pm ref leak bonanza
Second iteration of my endeavour to rid nouveau, radeon and amdgpu of
runtime pm ref leaks.
Patches 1 to 8 are identical to v1.
Patch 9 of v1 modified the DRM core to turn off all CRTCs on driver
unload. Based on feedback by Daniel Vetter, I've replaced this with
a helper to turn off all CRTCs, which is called by nouveau, radeon
and amdgpu on unload. In other words, this is now opt-in.
So
