Yes.  However Chen-Yu said that except for debugfs that cannot be
observed by user space anyway.

It's nice to have the NEW controls have multiple channels, which is what
this does.

No.  I checked using "amixer" - the names look fine,
"Left Mixer Left DAC Playback Switch".

With the patch series, amixer says:

numid=10,iface=MIXER,name='FM Playback Switch'
numid=6,iface=MIXER,name='FM Playback Volume'
numid=5,iface=MIXER,name='Line Boost Volume'
numid=9,iface=MIXER,name='Line Playback Switch'
numid=4,iface=MIXER,name='Line Playback Volume'
numid=1,iface=MIXER,name='Mic1 Boost Volume'
numid=11,iface=MIXER,name='Mic1 Playback Switch'
numid=2,iface=MIXER,name='Mic2 Boost Volume'
numid=12,iface=MIXER,name='Mic2 Playback Switch'
numid=7,iface=MIXER,name='Mic Playback Volume'
numid=18,iface=MIXER,name='Capture Source'
numid=19,iface=MIXER,name='Differential Line Source'
numid=8,iface=MIXER,name='Left Mixer Left DAC Playback Switch'
numid=15,iface=MIXER,name='Power Amplifier DAC Playback Switch'
numid=16,iface=MIXER,name='Power Amplifier Mixer Playback Switch'
numid=17,iface=MIXER,name='Power Amplifier Mute Switch'
numid=3,iface=MIXER,name='Power Amplifier Volume'
numid=14,iface=MIXER,name='Right Mixer Left DAC Playback Switch'
numid=13,iface=MIXER,name='Right Mixer Right DAC Playback Switch'
