From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Fix build errors and kconfig warning: since 'select' does not check Kconfig symbol dependencies, add that dependency explicitly. VIDEO_TW68 selects I2C_ALGOBIT, so it should depend on I2C to prevent build errors and warnings. warning: (CAN_PEAK_PCIEC && SFC && IGB && VIDEO_TW68 && DRM && FB_DDC && FB_VIA) selects I2C_ALGOBIT which has unmet direct dependencies (I2C) CC [M] drivers/i2c/algos/i2c-algo-bit.o ../drivers/i2c/algos/i2c-algo-bit.c: In function 'i2c_bit_add_bus': ../drivers/i2c/algos/i2c-algo-bit.c:658:33: error: 'i2c_add_adapter' undeclared (first use in this function) ../drivers/i2c/algos/i2c-algo-bit.c:658:33: note: each undeclared identifier is reported only once for each function it appears in ../drivers/i2c/algos/i2c-algo-bit.c: In function 'i2c_bit_add_numbered_bus': ../drivers/i2c/algos/i2c-algo-bit.c:664:33: error: 'i2c_add_numbered_adapter' undeclared (first use in this function) ../drivers/i2c/algos/i2c-algo-bit.c: In function 'i2c_bit_add_bus': ../drivers/i2c/algos/i2c-algo-bit.c:659:1: warning: control reaches end of non-void function [-Wreturn-type] ../drivers/i2c/algos/i2c-algo-bit.c: In function 'i2c_bit_add_numbered_bus': ../drivers/i2c/algos/i2c-algo-bit.c:665:1: warning: control reaches end of non-void function [-Wreturn-type] Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Hans Verkuil <hverkuil@xxxxxxxxx> --- drivers/media/pci/tw68/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- linux-next-20141001.orig/drivers/media/pci/tw68/Kconfig +++ linux-next-20141001/drivers/media/pci/tw68/Kconfig @@ -1,6 +1,6 @@ config VIDEO_TW68 tristate "Techwell tw68x Video For Linux" - depends on VIDEO_DEV && PCI && VIDEO_V4L2 + depends on VIDEO_DEV && PCI && VIDEO_V4L2 && I2C select I2C_ALGOBIT select VIDEOBUF2_DMA_SG ---help--- -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
