Thanks Hui. It looks like you found a few more Lenovo machines that
need this fix.
As well a going into the currently under development 4.18 kernel, the
new patch is in the 4.17.4 kernel:

ALSA: hda/realtek - Fix the problem of two front mics on more machines
commit e41fc8c5bd41b96bfae5ce4c66bee6edabc932e8 upstream.
We have 3 more Lenovo machines, they all have 2 front mics on them,
so they need the fixup to change the location for one of two mics.
Among these 3 Lenovo machines, one of them has the same pin cfg as the
machine with subid 0x17aa3138, so use the pin cfg table to apply fixup
for them. The rest machines don't share the same pin cfg, so far use
the subid to apply fixup for them.
