[PATCH stable 4.9 21/21] media: dvb_frontend: fix return error code

From: Florian Fainelli
Date: Fri Jun 05 2020 - 12:27:00 EST


From: Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxxxxx>

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@xxxxxxxxxxxxxx>
Thanks-to: Arnd Bergmann <arnd@xxxxxxxx>

To make me revisit this code.
