From: Steven Rostedt Date: Fri, 9 May 2025 19:26:57 +0000 (-0400) Subject: tracing: samples: Initialize trace_array_printk() with the correct function X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=1b0c192c92ea1fe2dcb178f84adf15fe37c3e7c8;p=linux-2.6-microblaze.git tracing: samples: Initialize trace_array_printk() with the correct function 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.
