Subject: media: dvb_frontend: get rid of get_property() callback
X-Git-Tag: v4.15-rc1~91^2~203
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=8f8a19fcc1a89b83d0ab6d7cf2bcdd272dbd4334;p=uclinux-h8%2Flinux.git

media: dvb_frontend: get rid of get_property() callback

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.
