Hello Ajay Singh,
The patch 9bc061e88054: "staging: wilc1000: added support to
dynamically add/remove interfaces" from Jun 26, 2019, leads to the
following static checker warning:
drivers/staging/wilc1000/wilc_wlan.c:497 wilc_wlan_handle_txq()
warn: missing error code here? 'wilc_wlan_txq_get_first()' failed.
drivers/staging/wilc1000/wilc_wlan.c
474 int wilc_wlan_handle_txq(struct wilc *wilc, u32 *txq_count)
475 {
476 int i, entries = 0;
477 u32 sum;
478 u32 reg;
479 u32 offset = 0;
480 int vmm_sz = 0;
481 struct txq_entry_t *tqe;
482 int ret = 0;
^^^^^^^
483 int counter;
484 int timeout;
485 u32 vmm_table[WILC_VMM_TBL_SIZE];
486 const struct wilc_hif_func *func;

491 if (wilc->quit)
492 goto out;

494 mutex_lock(&wilc->txq_add_to_head_cs);
495 tqe = wilc_wlan_txq_get_first(wilc);
496 if (!tqe)
497 goto out;
^^^^^^^^
Should this really be a success path?
498 dev = tqe->vif->ndev;
499 wilc_wlan_txq_filter_dup_tcp_ack(dev);
500 i = 0;
501 sum = 0;
502 do {
503 if (tqe && (i < (WILC_VMM_TBL_SIZE - 1))) {
