Total of 6 fixes and 3 cleanups - cleanups are last.
All of the fixes address problems that present themselves in situation when user engages in codec driver reload. Second condition to reproduce is two-step initialization of HDAudio codec - this is the case only for ASoC HDAudio bus driver as snd_hda_intel calls only compound function snd_hda_codec_new(). Once these conditions are met, several reload/unload scenarios end with null-ptr-deref and page faults. Goal of the series is to allow codec/bus driver reloading without any errors.
