Subject: Re: [PATCH] platinumfb: misplaced parenthesis
Date: Sun, 17 May 2009 13:53:00 +0200	[thread overview]

In-Reply-To: <1242426067.9691.4.camel@pasglop>

Since `+' has a higher precedence than the trinary operator `?', this
added `hres * (1 << color_mode)' to the boolean testing videomode
and depth.
