There's nothing driver-specific here, so teh #ifdef are kinda annoying ... And saving that one pointer in a really huge structure is somewhat silly. > return 0; > > +#ifdef CONFIG_DRM_FBDEV_EMULATION > err_cleanup_poll: > drm_kms_helper_poll_fini(dev); poll helpers aren't fbdev specific. Why do we need this? Is this just to shut up gcc?
