[PATCH 2/2] staging/iio: Make IIO depend on GENERIC_HARDIRQS

[Geert Uytterhoeven]

On m68k (which doesn't support generic hardirqs yet):

drivers/staging/iio/industrialio-trigger.c: In function âiio_trigger_pollâ:
drivers/staging/iio/industrialio-trigger.c:180: error: implicit declaration of function âgeneric_handle_irqâ
drivers/staging/iio/industrialio-trigger.c: In function âiio_trigger_poll_chainedâ:
drivers/staging/iio/industrialio-trigger.c:200: error: implicit declaration of function âhandle_nested_irqâ

drivers/staging/iio/industrialio-trigger.c:402: warning: initialization makes pointer from integer without a cast
drivers/staging/iio/industrialio-trigger.c: In function âiio_trig_subirqunmaskâ:

drivers/staging/iio/industrialio-trigger.c: In function âiio_allocate_triggerâ:
drivers/staging/iio/industrialio-trigger.c:432: error: implicit declaration of function âirq_alloc_descsâ
drivers/staging/iio/industrialio-trigger.c:455: error: âhandle_simple_irqâ undeclared (first use in this function)
drivers/staging/iio/industrialio-trigger.c:455: error: (Each undeclared identifier is reported only once
drivers/staging/iio/industrialio-trigger.c:455: error: for each function it appears in.)

Hence IIO_TRIGGER should depend on GENERIC_HARDIRQS.
But as IIO_TRIGGER and IIO_RING_BUFFER form a maze of dependencies and selects,
just make the whole IIO subsystem depend on GENERIC_HARDIRQS.

This dependency also covers !S390, so that one can be removed again.
