What about crtc's which were disabled before suspend, they will be enabled here unconditionally.
Indeed, fixed in v3.

These callbacks are obsolete and should not be used, additionally core don't call them if drm_device have DRIVER_MODESET flag.
Oh!, that might explain the struggle I had understanding when they were actually called. Removed in v3.

Nitpick, !drm_dev is always false, is not?
I guess so, platform_set_drvdata() is called during probe so it can't be null here. Removed in v3.

If you remove obsolete callbacks you can move suspend code here, the same for resume.

Ditto x2
Indeed, merged in v3.
Thank you very much for this review ! :)
