From: Laurent Pinchart <laurent.pinchart@ideasonboard.com> [ Upstream commit d2fcc9c2de1191ea80366e3658711753738dd10a ] The mipi_csis_events array ends with 6 non-error events, not 4. Update mipi_csis_log_counters() accordingly. While at it, log event counters in forward order, as there's no reason to log them backward.
