From: Xiong Zhou <jencce.kernel@xxxxxxxxx> This patch fixes build failure(randconfig) of next-20130501. When config I2C as m, BATTERY_BQ27x00 as y, here comes the failure. BATTERY_BQ27x00 depends on I2C according to the code. Failure message: drivers/built-in.o: In function `bq27x00_read_i2c': bq27x00_battery.c:(.text+0x1082a7): undefined reference to `i2c_transfer' drivers/built-in.o: In function `bq27x00_battery_init': bq27x00_battery.c:(.init.text+0x6085): undefined reference to `i2c_register_driver' bq27x00_battery.c:(.init.text+0x60c7): undefined reference to `i2c_del_driver' drivers/built-in.o: In function `bq27x00_battery_exit': bq27x00_battery.c:(.exit.text+0xbf0): undefined reference to `i2c_del_driver' make: *** [vmlinux] Error 1 Signed-off-by: Xiong Zhou <jencce.kernel@xxxxxxxxx> --- drivers/power/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/power/Kconfig b/drivers/power/Kconfig index 0d0b5d7..89e5ebd 100644 --- a/drivers/power/Kconfig +++ b/drivers/power/Kconfig @@ -152,6 +152,7 @@ config BATTERY_SBS config BATTERY_BQ27x00 tristate "BQ27x00 battery driver" + depends on I2C help Say Y here to enable support for batteries with BQ27x00 (I2C/HDQ) chips. -- 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
