From: Steven Rostedt <rostedt@goodmis.org>

When using trace_array_printk() on a created instance, the correct
function to use to initialize it is:

  trace_array_init_printk()

Not

  trace_printk_init_buffer()

The former is a proper function to use, the latter is for initializing
trace_printk() and causes the NOTICE banner to be displayed.

Fixes: 89ed42495ef4a ("tracing: Sample module to demonstrate kernel access to Ftrace instances.")
Fixes: 38ce2a9e33db6 ("tracing: Add trace_array_init_printk() to initialize instance trace_printk() buffers")
