num prefix itself take care of singular/plural, num_config would do
good.

Hardcoding without check ?

#define DEFAULT_NUM_CFG    1

if (cfgs->num_cfgs != DEFAULT_NUM_CFG)
      ret = -EINVAL;
      goto err;

cfg = &cfgs->llcc_config[DEFAULT_NUM_CFG - 1];

I would let others comment as well..

What (and how) should be const above?
