Subject: [PATCH 2/2] staging/iio: Make IIO depend on GENERIC_HARDIRQS
On m68k (which doesn't support generic hardirqs yet):
drivers/staging/iio/industrialio-trigger.c: In function ‘iio_trigger_poll’:
drivers/staging/iio/industrialio-trigger.c:180: error: implicit declaration of function ‘generic_handle_irq’

drivers/staging/iio/industrialio-trigger.c: In function ‘iio_trig_subirqunmask’:
drivers/staging/iio/industrialio-trigger.c:411: warning: initialization makes pointer from integer without a cast
drivers/staging/iio/industrialio-trigger.c: In function ‘iio_allocate_trigger’:
drivers/staging/iio/industrialio-trigger.c:432: error: implicit declaration of function ‘irq_alloc_descs’
drivers/staging/iio/industrialio-trigger.c:455: error: ‘handle_simple_irq’ 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.
