commented the insertion of the attribute name in patterns in the case of a string attribute notify_probe_by_file chooses a module based on a bus specific suffix dm_register_child_device has a parameter to optionally check the support for the node added scanning of bus devices after the boot filesystem is mounted fixed dm_rescan, locking was misbehaving fixed SYSTEM_DRIVER_REGISTRATION definition added B_DRIVER_MAPPING attributes for PCI and ACPI devices: %vendor%_%device% for PCI, hid_%hid% and type_%type% for ACPI moved acpi_device_module_info definition to public ACPI.h git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19394 a95241bf-73f2-0310-859d-f6bbb57e9c96
