Now, I understood.

By resetting one commit from v3.2, then now I got the expected result.

[makoto at vostro linux_mainline][v3.2_test]$ git reset HEAD^
Unstaged changes after reset:
M    Makefile
[makoto at vostro linux_mainline][v3.2_test]$ scripts/setlocalversion
-00105-g8696823-dirty

Thanks !!

Kind Regards,
Makoto Harada
