iio_trigger_poll() calls generic_handle_irq(). This function expects to

Was there an error or warning that lead to this patch?
Or can you point to what call in generic_handle_irq is making the
assumption that we are breaking?
Given this is using the irq_work framework I'm wondering if this is
a more general problem?
Basically more info please!
There is this series https://lkml.org/lkml/2020/3/6/433 which causes
generic_handle_irq() to issue an warning if it is called with IRQs on,
for a IRQ controller that can't handle it.
But I'm not convinced this applies to the IIO code, since this is a
purely virtual interrupt and is not interfering with any interrupt
controller hardware.
