FILE_LICENCE ( GPL2_OR_LATER   ) 

void isapnp_device_activation ( struct isapnp_device *  isapnp,
int  activation 
)

Activate or deactivate an ISAPnP device.

Parameters:
isapnp ISAPnP device
activation True to enable, False to disable the device
Return values:
None -
Exceptions:
None -
This routine simply activates the device in its current configuration, or deactivates the device. It does not attempt any kind of resource arbitration.
