We\nstart counting at 1.  However this code sets ctrl->pconfig[0].ch_mask = 128.\n\nBug #2:\nThere are SLIM_MAX_TX_PORTS (16) elements in tx_ch[] array but only\nQCOM_SDW_MAX_PORTS + 1 (15) in the ctrl->pconfig[] array so it corrupts\nmemory like Yongqin Liu pointed out.\n\nBug 3:\nLike Jie Gan pointed out, it erases all the tx information with the rx\ninformation.",
