2013-03-02iio: Fix build error seen if IIO_TRIGGER is defined but IIO_BUFFER is notGuenter Roeck1-3/+6
If CONFIG_IIO_TRIGGER is defined but CONFIG_IIO_BUFFER is not, the following build error is seen. drivers/iio/common/st_sensors/st_sensors_trigger.c:21:5: error: redefinition of ‘st_sensors_allocate_trigger’ In file included from drivers/iio/common/st_sensors/st_sensors_trigger.c:18:0: include/linux/iio/common/st_sensors.h:239:19: note: previous definition of ‘st_sensors_allocate_trigger’ was here drivers/iio/common/st_sensors/st_sensors_trigger.c:65:6: error: redefinition of ‘st_sensors_deallocate_trigger’ In file included from drivers/iio/common/st_sensors/st_sensors_trigger.c:18:0: include/linux/iio/common/st_sensors.h:244:20: note: previous definition of ‘st_sensors_deallocate_trigger’ was here This occurs because st_sensors_deallocate_trigger is built if CONFIG_IIO_TRIGGER is defined, but the dummy function is compiled if CONFIG_IIO_BUFFER is defined.
