The bug is a typo in the compatible string for the touchscreen node.
According to Documentation/devicetree/bindings/input/touchscreen/edt-ft5x06.yaml,
the correct compatible is "focaltech,ft8719", but the device tree used
"focaltech,fts8719".

Missing quotes.
[alias]
	sf = show --pretty='Fixes: %h (\"%s\")'

and then just `git sf commit`

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.

Do not attach (thread) your patchsets to some other threads (unrelated
or older versions). This buries them deep in the mailbox and might
interfere with applying entire sets. See also:

I don't think this patch is really correct, in the sdm845-mainline fork
there's a different commit which has some more changes to make the
touchscreen work:

https://gitlab.com/sdm845-mainline/linux/-/commit/2ca76ac2e046158814b043fd4e37949014930d70
