-Subject: [PATCH 15/29] printk: console: remove unnecessary safe buffer usage
-
-Upon registering a console, safe buffers are activated when setting
-up the sequence number to replay the log. However, these are already
-protected by @console_sem and @syslog_lock. Remove the unnecessary
-safe buffer usage.
