If the SSI has never been used and spi_init() is called, then the SSI receive FIFO is empty and remains so, so calling SPI_WAITFOREORx() at the end of spi_init() waits endlessly for SSI_SR.RNE to be set. Hence, this call must be removed in order to avoid a deadlock. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>
