Hi Mark, After merging the spi tree, today's linux-next build (powerpc allyesconfig) failed like this: drivers/spi/spi-dln2.c: In function 'dln2_spi_copy_from_buf': drivers/spi/spi-dln2.c:415:4: error: implicit declaration of function 'get_unaligned_le32' [-Werror=implicit-function-declaration] *d++ = get_unaligned_le32(s++); ^ Caused by commit ffb9ad0a47b4 ("spi: add support for DLN-2 USB-SPI adapter"). drivers/spi/spi-st-ssc4.c: In function 'spi_st_remove': drivers/spi/spi-st-ssc4.c:427:2: error: implicit declaration of function 'pinctrl_pm_select_sleep_state' [-Werror=implicit-function-declaration] pinctrl_pm_select_sleep_state(&pdev->dev); ^ drivers/spi/spi-st-ssc4.c: In function 'spi_st_runtime_resume': drivers/spi/spi-st-ssc4.c:453:2: error: implicit declaration of function 'pinctrl_pm_select_default_state' [-Werror=implicit-function-declaration] pinctrl_pm_select_default_state(dev); ^ Caused by commit cf9e9c98fa8c ("spi: Add new driver for STMicroelectronics' SPI Controller"). To me COMPILE_TEST means "this builds everywhere, make sure it doesn't break" ... not "lets set this and see if Stephen finds anything" :-) I reverted both commits for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
