Hi Mark, After merging the spi tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/spi/spi-loopback-test.c: In function 'spi_loopback_test_probe': drivers/spi/spi-loopback-test.c:292:7: error: 'check_rx_buf' undeclared (first use in this function) if (!check_rx_buf && (spi->master->mode_bits & SPI_LOOP)) { ^ Caused by commit b0632bfe5ec4 ("spi: loopback-test: added support for HW-loopback mode") I have used the spi tree from next-20160105 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
