From 582c52cb9cd2616ab0d41127b22ad56ee49d40b4 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Thu, 12 Dec 2013 13:44:14 -0300 Subject: [media] v4l: enable some IOCTLs for SDR receiver Enable stream format (FMT) IOCTLs for SDR use. These are used for negotiate used data stream format. Reorganise some some IOCTL selection logic.
