Commit 856c4663930988118d9f355aad66811dd6df06de had the line that
"bumps" the VERSION field in standard INQUIRY data removed. Add
it back and claim SPC-5 version compatibility, which matches with
the current version descriptor "SPC-5 (no version claimed)" used
for ZAC devices.

    You also need to specify the commit summary in (""). It's enough to 
specify 12 digits of SHA1 ID.
