Subject: [PATCH] vfio-ap: Assign default string "0" for empty APID and APQI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current script logic assigns an empty string to APID and APQI
when APQN consists entirely of zeros (e.g., "00.0000").
However, this behavior is incorrect, as "00" and "0000" are valid
values and should be represented as "0".
This commit ensures that the script assigns the default string “0”
to APID and APQI if their computed values are empty.
