Commit 0d96d5ead3f7 ("iio: humidity: Add triggered buffer support for
AM2315") added support for triggered buffers but those are only available
when IIO_TRIGGERED_BUFFER is selected. Currently we get warnings like:
drivers/iio/humidity/am2315.c: In function ‘am2315_trigger_handler’:
drivers/iio/humidity/am2315.c:186:2: error: implicit declaration of function
‘iio_push_to_buffers_with_timestamp’ [-Werror=implicit-function-declaration]
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: some warnings being treated as errors
scripts/Makefile.build:289: recipe for target 'drivers/iio/humidity/am2315.o' failed
Furthermore linking the kernel executable fails because triggered buffer
functions are never build.
Fix this by selecting IIO_TRIGGERED_BUFFER and IIO_BUFFER when the driver is
enabled.

If you say yes here you get support for the Aosong AM2315
relative humidity and ambient temperature sensor.
