Subject: [PATCH 11/17] common: Explicitly probe consoles earlier with deep probe
Date: Thu,  6 May 2021 11:28:55 +0200
Message-ID: <20210506092901.25461-12-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>

With deep probe support the device providing the console can come quite
late in the probe order. Make sure it's probed at postconsole_initcall
time as it used to be without deep probe support so that we get output
earlier.
