Subject: [PATCH] iio: pms7003: sleect IIO_TRIGGERED_BUFFER
Date:   Thu, 14 Mar 2019 10:00:52 +0100

Without IIO_TRIGGERED_BUFFER, this driver fails to link:

drivers/iio/chemical/pms7003.o: In function `pms7003_probe':
pms7003.c:(.text+0x21c): undefined reference to `devm_iio_triggered_buffer_setup'
pms7003.c:(.text+0x21c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `devm_iio_triggered_buffer_setup'

Fixes: a1d642266c14 ("iio: chemical: add support for Plantower PMS7003 sensor")
