[PATCH] PCI: disable msi mode in pci_disable_device
Brice said the pci_save_msi_state breaks his driver in his special usage (not in suspend/resume), as pci_save_msi_state will disable msi mode. In his usage, pci_save_state will be called at runtime, and later (after the device operates for some time and has an error) pci_restore_state will be called. In another hand, suspend/resume needs disable msi mode, as device should stop working completely. This patch try to workaround this issue. Drivers are expected call pci_disable_device in suspend time after pci_save_state. Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
