ncp2222: initialize buffer in build_expert_data
We do a bunch of conditional logic to fill in the buffer, and then were
checking
strlen(buffer) to see if we'd actually filled it in or not, but if we
hadn't
then the buffer was garbage and strlen(buffer) was throwing valgrind
warnings.
Ensure this works as intended by setting the first byte of the buffer
unconditionally at the beginning, so strlen(buffer) returns 0 as expected
in
that case.
