it should be iio_trigger_poll_chained(), not iio_trigger_poll(), since
this is an interrupt handler; this solves my WARN_ON()
iio_trigger_poll_chained() will call handle_nested_irq(), while
iio_trigger_poll() calls generic_handle_irq()
I modelled my code after ad91_adc which has iio_trigger_poll() in
at91_adc_eoc_trigger() together with disable_irq_nosync()/enable_irq() --
is this correct? not sure, my code uses threaded irq, at91_adc not so
comments?
thanks, regards, p.
