Thanks, quick review below.
Please try to send patches generated by you locally committing them (so
that they have a good commit message, and the author's name + email).
Once committed you can create a proper patch file like this:
git format-patch HEAD~1
(replace "1" with e.g. "5" to get the last five commits as patch files)

Yup, the handling seems hardcoded for fx2lafw here, but there's a
simpler fix for this.
You can generally use the boolean "devc->dslogic" (will be true if it's
a DSLogic device, false if it's another FX2 based device. But in this
case that won't be needed either, you can simply use devc->samplerates
and devc->num_samplerates in all cases (those are correctly set for
both device types) and only one code path will be needed.

This shouldn't be needed, protocol.h has the fx2lafw commands, the
DSLogic-specific ones in dslogic.h seem correct (haven't checked whether
those are actually used though).
