drm/udl: Drop explicit drm_mode_config_cleanup call
It's right above the drm_dev_put(). This allows us to delete a bit of onion unwinding in udl_modeset_init(). 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: Thomas Zimmermann <tzimmermann@suse.de> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Sean Paul <sean@poorly.run> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Emil Velikov <emil.l.velikov@gmail.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: "Noralf Trønnes" <noralf@tronnes.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-50-daniel.vetter@ffwll.ch
