Date: Mon, 13 May 2013 23:41:48 +0200 From: Peter Huewe <peterhuewe@....de> To: Arnaud Patard <arnaud.patard@...-net.org> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Peter Huewe <peterhuewe@....de>, Aaro Koskinen <aaro.koskinen@....fi>, Miguel Gómez <magomez@...lia.com>, devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org Subject: [PATCH 4/5] staging/xgifb: Remove unnecessary binary calculation in GetXG27FPBits If temp <= 2 no other bits than the lowest two (0x03) can be set anyway -> this operation can be removed.
