#     crypto: caam - fix copy of next buffer for xcbc and cmac
#     
#     Fix a side effect of adding xcbc support, when the next_buffer is not
#     copied.
#     The issue occurs, when there is stored from previous state a blocksize
#     buffer and received, a less than blocksize, from user. In this case, the
#     nents for req->src is 0, and the next_buffer is not copied.
#     An example is:
#     {
#             .tap    = { 17, 15, 8 },
#             .psize  = 40,
#             .np     = 3,
#             .ksize  = 16,
#     }
#     
#     Fixes: 12b8567f6fa4 ("crypto: caam - add support for xcbc(aes)")
