git patch

We have found and fixed a vulnerability using PVS-Studio tool. PVS-Studio is a
static code analyzer for C, C++ and C#: https://www.viva64.com/en/pvs-studio/

Analyzer warning: V547 Expression 'cdb[0] != 0x28 || cdb[0] != 0x2A' is always
true. Probably the '&&' operator should be used here. mfi_tbolt.c 1110
