From 7267b23859ba4188873e3d1c90c9b29031cc9356 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 1 Apr 2015 14:22:01 -0400 Subject: [PATCH] tracing: Add TRACE_SYSTEM_VAR to xhci-hcd New code will require TRACE_SYSTEM to be a valid C variable name, but some tracepoints have TRACE_SYSTEM with '-' and not '_', so it can not be used. Instead, add a TRACE_SYSTEM_VAR that can give the tracing infrastructure a unique name for the trace system.
