From 287cefd096b124874dc4d6d155f53547c0654860 Mon Sep 17 00:00:00 2001 From: Evgeny Plehov Date: Thu, 13 Sep 2012 10:13:30 -0300 Subject: [PATCH] [media] dvb_frontend: add multistream support Unify multistream support at the DVBAPI: several delivery systems allow it. Yet, each one had its own name. So, instead of adding a third version of this field, remove the per-standard naming, unifying it into a common name. The legacy code number can still be used by old applications. Version increased to 5.8.
