Yes, 'work_data' is allocated once on the first nonblocking RNG request
and reused for subsequent requests, but the memory is eventually freed
on device removal in atmel_sha204a_remove().

The memory might be retained unnecessarily after use when the device is
idle (probably negligible), but it's not a memory leak.

Best,
