From: Greg Kroah-Hartman
Date: Tue Dec 11 2018 - 10:57:16 EST


4.19-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mauro Carvalho Chehab <mchehab+samsung@xxxxxxxxxx>

commit 3420f65cbbd0555049bd02394bed33a0ef74d860 upstream.

The dvb_frontend core already checks for the frequencies. No
need for any additional check inside the driver.

It is part of the fixes for the following bug:
