Some video driver might returns -EPROBE_DEFER when probe timing, but logo init function doesn't care it. Thus, such kernel can't have logo when boot time. This patch solves this issue by exchanging current late_initcall to late_initcall_sync Signed-off-by: Takeshi Kihara <takeshi.kihara.df@renesas.com> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Cc: Laurent <laurent.pinchart@ideasonboard.com> Cc: Fabian Frederick <fabf@skynet.be> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: shimoda <yoshihiro.shimoda.uh@renesas.com> Cc: Koji Matsuoka <koji.matsuoka.xm@renesas.com> Cc: shiiba <naoya.shiiba.nx@renesas.com> Cc: sakato <ryusuke.sakato.bx@renesas.com> Cc: Hosoya <yoshifumi.hosoya.wj@renesas.com> Cc: Fukawa <tomoharu.fukawa.eb@renesas.com> Cc: Hien Dang <hien.dang.eb@renesas.com> Cc: Khiem Nguyen <khiem.nguyen.xt@renesas.com> Cc: Kouei Abe <kouei.abe.cp@renesas.com> Cc: Harunobu Kurokawa <harunobu.kurokawa.dn@renesas.com> Cc: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
