From 89edf36c177eec2b1a2cbbcaff48c4e9a946a190 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 23 Aug 2013 23:29:23 +0000 Subject: Add additional error handling to pcidev_readbar() callers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is mostly a leftover of Niklas' "remove exit call from pcidev_init" patch. While not explicitly necessary detecting errors early is usually a good idea. Corresponding to flashrom svn r1718.
