Hi everybody,
I got new HW from our supplier, a Fujitsu U727 and a U757 laptop, which have a headset jack. Attaching a headset, the microphone doesn't work. After some reading and trying various tools to understand the problem, I found hdajacksensetest, which showed a sense change for a seemingly wrong unconnected pin. Overriding this pins' config has fixed the headsets microphone, so now I have the attached kernel patch with a SND_HDA_PIN_QUIRK.
The pin config override itself looks OK, but the way to identify the machine is an open question. You've added the entries in alc269_pin_fixup_tbl[]. This table is for matching with a group of machines that have the same "fingerprint" by pin configs. Usually this is used for Dell laptops and such.
OTOH, if one quirk is needed only for one or two machines, using the PCI SSID (or codec SSID) is the easier way to go, and it's done by putting into alc269_fixup_tbl[].
After compiling the patched module (for 4.4), everything works as expected, but hdajackretask still shows the pin as unconnected, so I'm wondering, if I need to do something in addition?
If everything is working, why any more changes? :)

Is this normal behaviour? This is just a port to master, as we (Munich) are on Ubuntu Trusty with Xenial HWE (4.4 kernel).
Thanks for the review.

P.S. checkpatch.pl warned about too long lines for the SND_HDA_PIN_QUIRK. Should I fix that?

These laptops have a combined jack to attach headsets, the U727 on the left, the U757 on the right, but a headsets microphone doesn't work. Using hdajacksensetest I found that pin 0x19 changed the present state when plugging the headset, in addition to 0x21, but didn't have the correct configuration (shown as "Not connected").
So this sets the configuration to the same values as the headphone pin 0x21 except for the device type microphone, which makes it work correctly. With the patch the configured pins for U727 are
Pin 0x12 (Internal Mic, Mobile-In): present = No Pin 0x14 (Internal Speaker): present = No Pin 0x19 (Black Mic, Left side): present = No Pin 0x1d (Internal Aux): present = No Pin 0x21 (Black Headphone, Left side): present = No
