Lv Yunlong f973795a8d wireless: iwlwifi: Fix a double free in iwl_txq_dyn_alloc_dma ... In iwl_txq_dyn_alloc_dma, txq->tfds is freed at first time by: iwl_txq_alloc()->goto err_free_tfds->dma_free_coherent(). But it forgot to set txq->tfds to NULL. Then the txq->tfds is freed again in iwl_txq_dyn_alloc_dma by: goto error->iwl_txq_gen2_free_memory()->dma_free_coherent(). My patch sets txq->tfds to NULL after the first free to avoid the double free.
