#define GERR_RSP_FIFO_NOT_EMPTY   (-116)

The response FIFO was not empty after reading one packet of response.

Since the CMD/RSP path is a synchronous interface, each read command should create one and one response packet. This error means that more than one packet of data was in the FIFO while reading a response.
