ASoC: Merge tag 'v3.4-rc3' into for-3.5
Linux 3.4-rc3 contains a bunch of Tegra changes which are conflicting annoyingly with the new development that's going on for Tegra so merge it up to resolve those conflicts. Conflicts: sound/soc/soc-core.c sound/soc/tegra/tegra_i2s.c sound/soc/tegra/tegra_spdif.c
