4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Adrian Hunter <adrian.hun...@intel.com> commit 1c196a6c771c47a2faa63d38d913e03284f73a16 upstream. When a TIP packet is expected but there is a different packet, it is an error. However the unexpected packet might be something important like a TSC packet, so after the error, it is necessary to continue from there, rather than the next packet. That is achieved by setting pkt_step to zero.
