[PATCH] staging: iio: select IRQ_WORK for IIO_DUMMY_EVGEN

From: Arnd Bergmann
Date: Fri Oct 16 2015 - 18:30:40 EST


The iio dummy code was recently changed to use irq_work_queue, but
that code is compiled into the kernel only if IRQ_WORK is set, so
we can get a link error here:

drivers/built-in.o: In function `iio_evgen_poke':
(.text+0x208a04): undefined reference to `irq_work_queue'

This changes the Kconfig file to match what other drivers do.
