sound fixes for 4.16-rc6 

A series of small fixes in ASoC, HD-audio and core stuff:
 
 - A UAF fix in ALSA PCM core
 - Yet more hardening for ALSA sequencer
 - A regression fix for the previous HD-audio power_save option change
 - Various ASoC codec fixes (sgtl5000, rt5651, hdmi-codec, wm_adsp)
 - Minor ASoC platform fixes (AMD ACP, sun4i)
