    PM: tools: use canonical ftrace path · cf3e0251
    Ross Zwisler authored
    The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
    
    But, from Documentation/trace/ftrace.rst:
    
      Before 4.1, all ftrace tracing control files were within the debugfs
      file system, which is typically located at /sys/kernel/debug/tracing.
      For backward compatibility, when mounting the debugfs file system,
      the tracefs file system will be automatically mounted at:
    
      /sys/kernel/debug/tracing
    
    A few scripts in tools/power still refer to this older debugfs path, so
    let's update them to avoid confusion.
