Subject: [PATCH 4/5] dmesg: implement dmesg -n
Date: Mon, 12 Jun 2023 14:32:31 +0200	[thread overview]
Message-ID: <20230612123232.3071957-5-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230612123232.3071957-1-s.hauer@pengutronix.de>

Under Linux dmesg -n can be used to set the console loglevel. Implement
the same for barebox.
