drm: Integrate VRAM MM into struct drm_device
There's now a pointer to struct drm_vram_mm stored in struct drm_device. DRM drivers that use VRAM MM should use this field to refer to their instance of the data structure. Appropriate helpers are now provided as well. Adding struct drm_vram_mm to struct drm_device further avoids wrappers and boilerplate code in drivers. This patch implements default functions for callbacks in struct drm_driver and struct file_operations that use the struct drm_vram_mm stored in struct drm_device. Drivers that need to provide their own implementations can still do so. The patch also adds documentation for the VRAM helper library in general. v5: * set .llseek to no_llseek() from DRM_VRAM_MM_FILE_OPERATIONS v4: * cleanups from checkpatch.pl * document VRAM helper library Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-9-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
