It's not a core function, and the matching atomic functions are also not in the core. Plus the suspend/resume helper is also already there. Needs a tiny bit of open-coding, but less midlayer beats that I think.

Just some runtime PM fixes for some much less noticeable runtime PM ref tracking issues that I got reminded of when fixing some unrelated issues with nouveau. Changes since v1: * Don't fix CRTC RPM code in dispnv04, because it's not actually doing anything in the first place. Just get rid of it. - imirkin Lyude Paul (2): drm/nouveau/dispnv04: Remove runtime PM drm/nouveau/dispnv50:

The following patchset remove use of the deprecated drmP.h header file in the nouveau driver(s). As preparation a dependency on drm_os_linux.h is dropped. The list of include files are sorted and are in some cases divided up in blocks of linux/* drm/* etc. The removal is divided up in a few patches that was the logical steps to remove the use of drmP.h.

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

This is the latest version of https://patchwork.freedesktop.org/series/45862/ . One new patch has been added that also addresses some additional issues I found with pmops_runtime_idle that would stop nouveau from suspending the GPU when running under X. Additionally, "drm/nouveau: Fix runtime PM leak in nv50_disp_atomic_commit()" has had it's CC to stable removed. Lyude Paul (3):

The NULL initialization of the pointers assigned by kzalloc() or kunit_kzalloc() first is not necessary, because if the kzalloc() or kunit_kzalloc() failed, the pointers will be assigned NULL, otherwise it works as usual. so remove it. Ruan Jinjie (7): drm/amdkfd: Remove unnecessary NULL values drm/amd/display: Remove unnecessary NULL values drm/msm: Remove unnecessary NULL values

In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

match_string() returns the array index of a matching string. Use it instead of the open-coded implementation.
