Merge tag 'asoc-fix-v4.2-rc3' into asoc-fix-topology
ASoC: Fixes for v4.2 A lot of small fixes here, a few to the core: - Fix for binding DAPM stream widgets on devices with prefixes assigned to them - Minor fixes for the newly added topology interfaces - Locking and memory leak fixes for DAPM - Driver specific fixes
