potential bug in peer_data_storage

Question

Hi I think this might be a potential bug in peer_data_storage.c 
 ret = fds_register(fds_evt_handler);
if (ret != NRF_SUCCESS)
{
return NRF_ERROR_INTERNAL;
}
ret = fds_init();
if (ret != NRF_SUCCESS)
{
return NRF_ERROR_NO_MEM;
} 
 fds_register is called before fds_init(). Why is this? surely you should init before registering ?

Hi, 
 This is not a bug. The explanation can be found at the FDS Usage section in the infocenter: 
 
 Initialization, like all other operations in FDS that involve writing or erasing flash memory, is an asynchronous operation. Completion of the operation is reported to the application through a callback. Therefore, before initializing FDS, you must register a callback handler to handle FDS events.
