Subject: [PATCH v4 10/27] xen/video: hdlcd: Use early_printk instead of printk
Date: Fri, 13 Sep 2013 13:49:17 +0100 [thread overview]
Message-ID: <1379076574-28316-11-git-send-email-julien.grall@linaro.org> (raw)
In-Reply-To: <1379076574-28316-1-git-send-email-julien.grall@linaro.org>
The video driver is initialized before the console is correctly set up.
Therefore, printk will never output if there is no serial configured.
