Introduce the pm8001_ccb_alloc() and pm8001_ccb_free() helpers to replace the typical code patterns: res = pm8001_tag_alloc(pm8001_ha, &ccb_tag); if (res) ... ccb = &pm8001_ha->ccb_info[ccb_tag]; ccb->device = pm8001_ha_dev; ccb->ccb_tag = ccb_tag; ccb->task = task; ccb->n_elem = 0; and ccb->task = NULL; ccb->ccb_tag = PM8001_INVALID_TAG; pm8001_tag_free(pm8001_ha, tag); With the simpler function calls: ccb = pm8001_ccb_alloc(pm8001_ha, pm8001_ha_dev, task); if (!ccb) ... and pm8001_ccb_free(pm8001_ha, ccb); The pm8001_ccb_alloc() helper ensures that all fields of the ccb info structure for the newly allocated tag are all initialized, except the buf_prd field. The pm8001_ccb_free() helper clears the initialized fields and the ccb tag to ensure that iteration over the adapter ccb_info array detects ccbs that are in use. All call site of the pm8001_tag_alloc() function that use a ccb info associated with an allocated tag are converted to use the new helpers.
