ASoC: rockchip: i2s: fix error defination of transmit data level
According to description about "Transmit Data Level", This bit field controls the level at which a DMA request is made by the transmit logic. It is equal to the watermark level. That is, the dma_tx_req signal is generated when the number of valid data entries in the TXFIFO (TXFIFO0 if CSR=00 TXFIFO1 if CSR=01 TXFIFO2 if CSR=10 TXFIFO3 if CSR=11) is equal to or below this field value. Different to receive data level, transmit data level does not need to "-1". Signed-off-by: Jianqun Xu <jay.xu@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
