From c46980f6d2135ade345dadc1fb1f1f4c8bbf255a Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 14 Oct 2008 07:04:38 -0400 Subject: cmd_spi: remove broken signed casting for display Since we're working with unsigned data, you can't apply a signed pointer cast and then attempt to print the result. Otherwise you get wrong output when the sign bit is set like "0xFF" incorrectly extended to "0xFFFFFFFF".
