So this is the second version of the patch so it should be marked as
such. You're using patman, which means you should have something like:
Series-version: 2
Series-changes: 2
- Word wrapped patch description.
- Removed "Author" from patch description.
- Fixed whitespace around "en_pp3300_dx_edp"
Then patman will translate that in the right thing. In the next
version of the patch you'd _update_ "Series-version" to 3. Then you'd
leave the Series-changes: 2 stuff and add a new Series-changes: 3
section talking about the changes from 2 to 3. Running `patman
--full-help` should talk about all this stuff.
As a nit, I'll also mention that your subject line for the patch
shouldn't end with a period.

sc7280-herobrine-herobrine-r0.dtb has been removed from the Qualcomm
tree. This makes your patch not apply unless I do "git am -3". Can you
update the Qualcomm branch, rebase, and send a v3?

Hrm, looking at these rt5682s.dts files it feels like it could be done
a little better. It would probably be slightly better/shorter to base
on the non-rt5682s version, AKA:
#include "sc7180-trogdor-wormdingler-rev1-boe.dts"
/ {
model = "Google Wormdingler rev1+ (BOE, rt5682s)";
compatible = "google,wormdingler-sku1025", "qcom,sc7180";
};
&alc5682 {
compatible = "realtek,rt5682s";
realtek,dmic1-clk-pin = <2>;
realtek,dmic-clk-rate-hz = <2048000>;
};
&sound {
compatible = "google,sc7180-trogdor";
model = "sc7180-rt5682s-max98357a-1mic";
};
...similar for the other -rt5682s file...
Not sure why I didn't suggest that originally when reviewing
downstream at <https://crrev.com/c/3305627>. I guess I was younger
then.
It'd be nice if you could do this in a v3, though I suppose we could
always do it as a future cleanup.
It would also be handy if you could delete the keypad num-rows /
num-columns in wormdingler.dts in a v3 like Stephen did for
coachz/homestar. That'll save us from having to do a separate patch
for it. Buttons/switches won't work until we get the input fix in
linux-next, but that shouldn't be a huge deal, especially since
wormdinger wasn't even supported upstream at all until this patch.
