Yes. "Do this. Also do that" is usually a sign that the patch should be split.

Please excuse me, I can't fully understand. So are the files the same or not?
There is a simple mental experiment regarding the file names: you
should be able to have a single host rootfs, which supports working
with all of your modems at the same time, without modifications.
So if modem A and modem B might use file foo.bar and the file is the
same for all SDX55 modems, it's fine to have it in qcom/sdx55m/ or in
qcom/sdx55m/foxconn. If it is different depending on the end-device,
it should go to the qcom/sdx55m/foxconn/devname/ .
