From: Heinrich Schuchardt Date: Wed, 17 Jun 2020 19:52:44 +0000 (+0200) Subject: log: don't show function by default X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=3c21d7738a793bb7713df5ac4de434c680fa249f;p=u-boot.git log: don't show function by default The name of the function emitting a log message may be of interest for a developer but is distracting for normal users. See the example below: try_load_entry() Booting: Debian Make the default format for log messages customizable. By default show only the message text.
