Instead rely on the automatic clean, for which we just need to check that drm_mode_config_init succeeded. To avoid an inversion in the cleanup we also have to move the dev_private allocation over to drmm_kzalloc. This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Acked-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-29-daniel.vetter@ffwll.ch
