Mark has mentioned quite a few times that this patch subject is
incorrect. ASoC patch subjects should start with "ASoC: ". You can see
this by running:
git log -- sound/soc/tegra/
I'd suggest the following:
AsoC: tegra_max98090: honor headphone detect GPIO polarity
Set the invert property for the headphone jack depending on the GPIO flag in the
device-tree. This is similar to what is done for tegra_rt5640.
diff --git a/sound/soc/tegra/tegra_max98090.c b/sound/soc/tegra/tegra_max98090.c

Did you run checkpatch? It should complain about > 80 columns, and I
suspect about the unnecessary brackets around that expression. In fact,
checkpatch indicates quite a few other warnings and errors.
The logic in this patch looks OK. Do the relevant DT files all have the
correct GPIO flags already? That'd be nice!
