commit 4302a596 upstream. When used via spidev with more than one messages to tranfer via SPI_IOC_MESSAGE the current implementation would return with -EINVAL, since bits_per_word and speed_hz are set in all transfer structs. And in the 2nd loop status will stay at -EINVAL as its not overwritten again via fsl_spi_setup_transfer(). This patch changes this behavious by first checking if one of the messages uses different settings. If this is the case the function will return with -EINVAL. If not, the messages are transferred correctly.
