From: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

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:
https://bugzilla.opensuse.org/show_bug.cgi?id=1116374
