Subject: [PATCH 06/13] v4l: add type field to v4l2_modulator struct
Date: Wed,  2 Sep 2015 00:59:22 +0300	[thread overview]
Message-ID: <1441144769-29211-7-git-send-email-crope@iki.fi> (raw)
In-Reply-To: <1441144769-29211-1-git-send-email-crope@iki.fi>

Add type field to that struct like it counterpart v4l2_tuner
already has. We need type field to distinguish different tuner
types from each others for transmitter too.
