Subject: [PATCH v5 6/6] drm: Make the nomodeset message less sensational
Date:   Fri, 12 Nov 2021 14:32:30 +0100
Message-Id: <20211112133230.1595307-7-javierm@redhat.com>

The message printed when nomodeset is present in the kernel command line
makes it look as if the parameter must never be used and it's a bad idea.

But there are valid reasons to use this parameter and the message should
not imply otherwise. Change the text to be more accurate and restrained.
