Audit this piece of code:

437         table = devm_kcalloc(dev, AVS_PSTATE_MAX + 1, sizeof(*table),
438                              GFP_KERNEL);
439         if (!table)
440                 return ERR_PTR(-ENOMEM);
441 
442         for (i = AVS_PSTATE_P0; i <= AVS_PSTATE_MAX; i++) {
443                 ret = brcm_avs_set_pstate(priv, i);
444                 if (ret)
445                         return ERR_PTR(ret);
446                 table[i].frequency = brcm_avs_get_frequency(priv->base);
447                 table[i].driver_data = i;
448         }
449         table[i].frequency = CPUFREQ_TABLE_END;
