Manipulate device quiet flag
Part of device_quiet(9).
Usage

Overview
Each device has a quiet flag associated with it. A device is verbose by default when it is created but may be quieted to prevent printing of the device identification string during attach and printing of a message during detach. To quiet a device, call device_quiet() during a device driver probe routine. To re-enable probe messages, call device_verbose(). To test to see if a device is quieted, call device_is_quiet().
Devices are implicitly marked verbose after a driver detaches.
