drm/fb-helper: Remove return value from drm_fbdev_generic_setup()
Generic fbdev emulation is a DRM client. Drivers should invoke the setup function, but not depend on its success. Hence remove the return value. v3: * document stricter requirements for call sequence v2: * warn if fbdev device has not been registered yet * document the new behavior * convert the existing warning to the new dev_ interface Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Acked-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200408082641.590-11-tzimmermann@suse.de
