From: Vegard Nossum <vegard.nossum at oracle.com>

commit 01cc5235604d61018712c11a14d74230f6a38bf4 upstream.

Ran into this on UML:

drivers/iio/accel/stk8ba50.c: In function ‘stk8ba50_data_rdy_trigger_set_state’:
drivers/iio/accel/stk8ba50.c:163:9: error: implicit declaration of function ‘iio_trigger_get_drvdata’ [-Werror=implicit-function-declaration]

iio_trigger_get_drvdata() is defined only when IIO_TRIGGER is selected.
