Change the zinger software version returned by VDO_CMD_READ_INFO to report the commit count portion of the version string to make the software version automatically change. This software version is important for debugging and is printed to PD console every time a zinger is attached. BUG=none BRANCH=none TEST=load onto zinger and samus, plug in zinger and see: Dev:1 SW:2147 RW:0 compare to the version string in zinger binary and we see: zinger_v1.1.2147-...
