Thread-topic:	[PATCH][VTD] fix ASSERT failure when build with debug=y

Keir,

Please ignore this patch for now as it caused problem on certain systems.  We 
will submit a separate patch to clean up dev_lock and pci_devs_lock usage.

For people encounter the ASSERTION failure.  The workaround is to remove ASSERT 
in pci_get_pdev() and pci_get_pdev_by_domain().

Allen

Acquire dev_lock before calling pci_dev_get_pdev_by_domain() to fix an ASSERT 
failure when build with debug=y.
