From: Jiri Slaby Date: Tue, 22 Sep 2009 23:47:41 +0000 (-0700) Subject: video: console, use DIV_ROUND_UP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a4a83d2ed83da0c4b45289ca72f10205aa96589;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git video: console, use DIV_ROUND_UP Use DIV_ROUND_UP explicitly instead of manual shifts and adds. It makes the code more readable and consistent (sometimes there were shifts, sometimes divs). There is no change on the assembly level (compilers should do the right job).
