sound fixes for 3.18-rc2

Here are a chunk of small fixes since rc1: two PCM core fixes, one is
 a long-standing annoyance about lockdep and another is an ARM64 mmap
 fix.  The rest are a HD-audio HDMI hotplug notification fix, a fix for
 missing NULL termination in Realtek codec quirks and a few new
 device/codec-specific quirks as usual.
