The recent commit f83bb2592482 ("ALSA: hda/conexant: Add quirk for
LENOVO 20149 Notebook model") introduced a quirk for the device with
17aa:3977, but this caused a regression on another model (Lenovo
Ideadpad U31) with the very same PCI SSID. And, through skimming over
the net, it seems that this PCI... | ```diff

Make use of this external PCS driver and drop the now reduntant

As a nice side effect the SGMII registers can now also more easily be
inspected for debugging via /sys/kernel/debug/regmap.

Since io_uring does nonblocking connect requests, if we do two repeated
ones without having a listener, the second will get -ECONNABORTED rather
than the expected -ECONNREFUSED. Treat -ECONNABORTED like a normal retry
condition if we're nonblocking, if we haven't already seen it.
