The following kernel linkage error:
st_lsm6dsx_core.o: in function `st_lsm6dsx_sw_buffers_setup':
st_lsm6dsx_core.c:2578: undefined reference to `devm_iio_triggered_buffer_setup_ext'
is caused by the fact that the object owning devm_iio_triggered_buffer_setup_ext()
(drivers/iio/buffer/industrialio-triggered-buffer.o) is allowed to be
built as module when its user (drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c)
is built-in.
The st_lsm6dsx driver already has a "select IIO_BUFFER", so add another
select for IIO_TRIGGERED_BUFFER, to make that option follow what is set
for the st_lsm6dsx driver. This is similar to what other iio drivers do.
Fixes: 2cfb2180c3 ("iio: imu: st_lsm6dsx: introduce sw trigger support")

Say yes here to build support for STMicroelectronics LSM6DSx imu
|
|
sensor. Supported devices: lsm6ds3, lsm6ds3h, lsm6dsl, lsm6dsm,
|
|
ism330dlc, lsm6dso, lsm6dsox, asm330lhh, asm330lhhx, lsm6dsr,
|
|
lsm6ds3tr-c, ism330dhcx, lsm6dsrx, lsm6ds0, lsm6dsop, lsm6dstx,
|

lsm6dsv, lsm6dsv16x, lsm6dso16is, ism330is, lsm6dst and the
|
|
accelerometer/gyroscope of lsm9ds1.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called st_lsm6dsx.
