2018-10-11drm/nouveau: Start using new drm_dev initialization helpersLyude Paul
Per the documentation in drm_get_pci_dev(), this function is deprecated and shouldn't be used anymore. As it turns out, we're going to need to stop using drm_get_pci_dev() anyway in order to allow us to turn off the card before full system shutdowns, otherwise we'll hit race conditions with userspace while trying to tear down the card on shutdown. So, start using drm_dev_get() and drm_dev_put(), and just turn our load/unload callbacks into open coded init/fini() functions.

2018-10-11drm/nouveau: Refactor nvXX_backlight_init()Lyude Paul
There's literally no difference between any of the backlight init functions besides the backlight properties they set and the backlight callbacks that they set, so move all of the duplicated backlight init code out of there and into nouveau_backlight_init(). This gets rid of a lot of copy pasta! Changes since v1: - Some of the pre-refactor callbacks were storing nv_encoder in callback data for the backlight devices that they registered, as opposed to nouveau_drm. This got missed and caused some bugs that didn't originally appear on my setup (NULL kernel derefs) for some reason. So, fix this by finding the nouveau_encoder in nouveau_backlight_init(), and using that as the callback data for all gens instead even if they don't care about the encoder.

According to the documentation on the drm_connector->late_register() hook, the ->late_register() hook should be used for adding extra connector-related devices. Vice versa, the ->early_unregister() hook is meant to be used for removing those devices. So: gut nouveau_drm->bl_list and nouveau_drm->backlight, and replace them with per-connector backlight structures. Additionally, move backlight registration/teardown into the ->late_register() and ->early_unregister() hooks so that DRM can give us a chance to remove the backlight before the connector is even removed. This appears to fix the problem once and for all. Changes since v2: - Use NV_INFO_ONCE for printing GMUX information, since otherwise this will end up printing that message for as many times as we have connectors Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Karol Herbst <kherbst@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2018-10-10drm/amdgpu: Suppress keypresses from ACPI_VIDEO eventsLyude Paul
Currently we return NOTIFY_DONE for any event which we don't think is ours. However, many laptops will send more then just an ATIF event and will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't check for this, we return NOTIFY_DONE which causes a keypress for the ACPI event to be propogated to userspace. This is the equivalent of someone pressing the display key on a laptop every time there's a hotplug event. So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses from them.
