Alexander Wuerstlein 0483fff4d0 iio hid-sensor-trigger: add Kconfig depends on IIO_BUFFER
Building a kernel with my configuration failed with:
> drivers/built-in.o: In function `hid_sensor_setup_batch_mode': staging/drivers/iio/common/hid-sensors/hid-sensor-trigger.c:104: undefined reference to `iio_buffer_set_attrs'
which is fixed by this patch.

Say yes here to build support for HID sensor to use
HID sensor common processing for attributes and IIO triggers.
There are many attributes which can be shared among multiple
HID sensor drivers, this module contains processing for those
attributes.
config HID_SENSOR_IIO_TRIGGER
tristate "Common module (trigger) for all HID Sensor IIO drivers"
depends on HID_SENSOR_HUB && HID_SENSOR_IIO_COMMON && IIO_BUFFER
select IIO_TRIGGER
help
Say yes here to build trigger support for HID sensors.
Triggers will be send if all requested attributes were read.
If this driver is compiled as a module, it will be named
hid-sensor-trigger.
