e435e49fbe4matroxfb: fix problems with display stabilitycommit 8c651311a3a08c1e4815de6933e00a760e498dae upstream. Regression caused in 2.6.23 and then despite repeated requests never fixed or dealt with (Petr promised to sort it in 2008 but seems to have forgotten). Enough is enough - remove the problem line that was added. If it upsets someone they've had two years to deal with it and at the very least it'll rattle their cage and wake them up. ...
