Subject: [PATCH v5 6/6] drm: Make the nomodeset message less sensational
Date: Fri, 12 Nov 2021 14:32:30 +0100	[thread overview]
Message-ID: <20211112133230.1595307-7-javierm@redhat.com> (raw)
In-Reply-To: <20211112133230.1595307-1-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.

Changes in v4:
- Don't mention DRM drivers in the kernel message and instead explain
  that only the system framebuffer will be available.
