[Intel-gfx] [PATCH 05/37] drm/pci: Deprecate drm_pci_init/exit completely
Daniel Vetter
daniel.vetter at ffwll.ch
Wed May 24 14:51:40 UTC 2017
The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.
