Subject: [PATCH] drm/i915: Fix unset margins flag in drm_mode_parse_command_line_for_connector
Date: Wed, 4 May 2011 17:18:13 -0500 (CDT)
Message-ID: <alpine.DEB.1.10.1105041714320.8641@cnc.isely.net> (raw)
In-Reply-To: <alpine.DEB.1.10.1105041703500.8641@cnc.isely.net>


The drm function which parses a mode into a standard mode line is
computing the "margins" flag but then failing to copy that parameter
into the parsed structure output.  This seems to leave the field in a
random state, which unfortunately influences the results when the
parsed results are then subsequently used to calculate a mode line.
The fix here is obvious: ensure the the margins flag is properly
initialized in the result structure at the end of the parse operation.
