From ef1bba28bfe68ef3c0488feeaabd3e8bc523130c Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Tue, 23 Dec 2008 03:09:53 +0000 Subject: [PATCH] net: sfc: Use pci_clear_master() to disable bus mastering pci_disable_device() disables many features, like MSI-X, which we never reenable in efx_reset(). Further, calls to pci_enable_device() and pci_disable_device() must be matched since the nesting count was introduced, so switch to using pci_clear_master() instead.
