From db3ea7819d035ff01c8260fce364511adfae0eaa Mon Sep 17 00:00:00 2001 From: Sathya Perla Date: Mon, 22 Aug 2011 19:41:52 +0000 Subject: [PATCH] be2net: get rid of memory mapped pci-cfg space address Get rid of adapter->pcicfg and its use. Use pci_config_read/write_dword() instead. Signed-off-by: Sathya Perla Signed-off-by: David S.
