Subject[PATCH 4.9 102/191] media: dvb_frontend: get rid of get_property() callback
Date
From: Mauro Carvalho Chehab <mchehab@s-opensource.com>

commit 8f8a19fcc1a89b83d0ab6d7cf2bcdd272dbd4334 upstream

Only lg2160 implement gets_property, but there's no need for that,
as no other driver calls this callback, as get_frontend() does the
same, and set_frontend() also calls lg2160 get_frontend().

So, get rid of it.
