* drm/amdgpu: initialize the context reset_counter in amdgpu_ctx_initNicolai Hähnle2016-10-121-0/+3

* drm/amdgpu: use .early_unregister hook to remove DP AUX i2cGrazvydas Ignotas2016-10-121-1/+12
| | | | | | | | | | | | | | | | | | | When DisplayPort AUX channel i2c adapter is registered, drm_connector's kdev member is used as a parent, so we get sysfs structure like: /drm/card1/card1-DP-2/i2c-12 Because of that, there is a problem when drm core (and not the driver) calls drm_connector_unregister(), it removes parent sysfs entries ('card1-DP-2' in our example) while the i2c adapter is still registered. Later we get a WARN when we try to unregister the i2c adapter: WARNING: CPU: 3 PID: 1374 at fs/sysfs/group.c:243 sysfs_remove_group+0x14c/0x150 sysfs group ffffffff82911e40 not found for kobject 'i2c-12' To fix it, we can use the .early_unregister hook to unregister the i2c adapter before drm_connector's sysfs is torn down.

| * drm/amdgpu: warn if dp aux is still attached on freeGrazvydas Ignotas2016-10-062-1/+4
| | | | | | | | | | | | | | | | | | | | | | If this happens (and it recently did), we free a structure while part of it is still in use, which results in non-obvious crashes. The way it's detached is not trivial (DRM core has to call the connector .destroy callback and things must be torn down in the right order), so better detect it and warn early.

Various error paths may result in amdgpu_fini() being called before .late init is done, so late_init needs to be tracked to avoid unexpected or multiple .late_fini() calls.
