Subject: [RFC 05/10] fbmon: Add extra video helper
Date: Wed, 17 Apr 2013 16:17:17 +0100	[thread overview]
Message-ID: <1366211842-21497-6-git-send-email-pawel.moll@arm.com> (raw)
In-Reply-To: <1366211842-21497-1-git-send-email-pawel.moll@arm.com>

This function converts the fb_var_screeninfo to the videomode
structure, to be used in fbdev drivers working with the
Common Display Framework.
