[PATCH spi-next 2/3] spi: spi-fsl-lpspi: fsl_lpspi_transfer_one(): directly return ret

[Marc Kleine-Budde]

Both fsl_lpspi_dma_transfer() and fsl_lpspi_pio_transfer() only return
negative error values in case of error or 0 in case of success.

Directly return ret, there is no need to check for positive error values
and return them as 0.
