Hi Wolfram, After merging the i2c tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/i2c/i2c-core-base.c: In function 'get_scl_gpio_value': drivers/i2c/i2c-core-base.c:137:9: error: implicit declaration of function 'gpiod_get_value_cansleep' [-Werror=implicit-function-declaration] return gpiod_get_value_cansleep(adap->bus_recovery_info->scl_gpiod); ^ drivers/i2c/i2c-core-base.c: In function 'set_scl_gpio_value': drivers/i2c/i2c-core-base.c:142:2: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration] gpiod_set_value_cansleep(adap->bus_recovery_info->scl_gpiod, val); ^ Caused by commit 3991c5c80bea ("i2c: Switch to using gpiod interface for gpio bus recovery") It is declared in include/linux/gpio/consumer.h which is not directly included by drivers/i2c/i2c-core-base.c ... I have used the i2c tree from next-20171127 for today. -- Cheers, Stephen Rothwell -- 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
