Hi,
+static void tasdevice_select_cfg_blk(void *pContext, int conf_no,
+ unsigned char block_type)
+{
+ struct tasdevice_priv *tas_dev = (struct tasdevice_priv *) pContext;
+ struct tasdevice_rca *rca = &(tas_dev->rcabin);
+ struct tasdevice_config_info **cfg_info = rca->cfg_info;
+ struct tasdev_blk_data **blk_data;
+ int j, k, chn, chnend;
+
+ if (conf_no >= rca->ncfgs || conf_no < 0 || !cfg_info) {
+ dev_err(tas_dev->dev, "conf_no should be not more than %u\n",
+ rca->ncfgs);
+ return;
+ }
+ blk_data = cfg_info[conf_no]->blk_data;
+
+ for (j = 0; j < (int)cfg_info[conf_no]->real_nblocks; j++) {
+ unsigned int length = 0, rc = 0;
+
+ if (block_type > 5 || block_type < 2) {
+ dev_err(tas_dev->dev,
+ "block_type should be in range from 2 to 5\n");
+ break;
+ }
+ if (block_type != blk_data[j]->block_type)
+ continue;
+
+ for (k = 0; k < (int)blk_data[j]->n_subblks; k++) {
+ if (cfg_info[conf_no]->blk_data[j]->dev_idx) {
Just use "blk_data[j]->dev_idx"?
+ chn = blk_data[j]->dev_idx - 1;
+ chnend = blk_data[j]->dev_idx;
+ } else {
+ chn = 0;
+ chnend = tas_dev->ndev;
+ }

+ /* Several kinds of dsp/algorithm firmwares can run on tas2781,
+ * the number and size of blk are not fixed and different among
+ * thest firmwares.
these?
