clRetainDevice - Increments the devices reference count.
cl_int clRetainDevice(cl_device_id device);
Increments the device reference count if device is a valid sub-device created by a call to clCreateSubDevices(3clc). If device is a root level device i.e. a cl_device_id returned by clGetDeviceIDs(3clc), the device reference count remains unchanged.
Returns CL_SUCCESS if the function is executed successfully or the device is a root-level device. Otherwise, it returns one of the following errors:
clCreateSubDevices(3clc), clGetDeviceIDs(3clc), clReleaseDevice(3clc)
