Subject: [PATCH 02/14] common: console: add log_dprint to print to file descriptor
Date: Tue, 13 Apr 2021 00:34:50 +0200 [thread overview]
Message-ID: <20210412223502.29691-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210412223502.29691-1-a.fatoum@pengutronix.de>
It can be useful to dump the log into the file, e.g. when doing an
update from a USB flash drive with no serial peer attached. Board code
could use log_dprint to dump the log onto the drive. Add a function
to facilitate this.
