    Subject[PATCH stable 4.9 21/21] media: dvb_frontend: fix return error code
    Date
    From: Mauro Carvalho Chehab <mchehab@s-opensource.com>

    commit 330dada5957e3ca0c8811b14c45e3ac42c694651 upstream

    The correct error code when a function is not defined is
    -ENOTSUPP. It was typoed wrong as -EOPNOTSUPP, with,
    unfortunately, exists, but it is not used by the DVB core.

    Thanks-to: Geert Uytterhoeven <geert@linux-m68k.org>
    Thanks-to: Arnd Bergmann <arnd@arndb.de>

    To make me revisit this code.

    Fixes: a9cb97c3e628 ("media: dvb_frontend: be sure to init dvb_frontend_handle_ioctl() return code")
