From fc0012ec533def054e1ac57d54ed781fc0ab6b71 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Thu, 12 Sep 2013 23:01:29 +0200 Subject: [PATCH] pata_isapnp: Don't use invalid I/O ports The test for 2nd I/O port validity is broken (reversed): On devices with no control port, the driver attempts to use invalid port 0, resulting in logs full of bad_io_access errors. On devices with control port, the driver does not use it.
