search for: postclose

This series fixes a number of use-after-frees in nouveau's postclose() handler. It was discovered by pointing IGT's core_hotunplug tests at a nouveau device, but the steps to reproduce it are simple: 1. Open the device file 2. Unbind the driver or remove the device 3. Close the file opened in step 1. During the device removal, the nouveau_drm structure is de-a...

After switching all drivers' fbdev emulation to DRM client, the old fbdev hooks are now obsolete. Only amgdpu and nouveau still use them in a several places. Remove the hooks from the drivers and the DRM core. The series would ideally be merged at once via drm-misc-next. v2: - call vga_switcheroo_process_delayed_switch() from drm_lastclose() (Sima) - documentation updates Thomas
