From: Felix Gu <ustc.gu@gmail.com>

commit 36f6d4db3c5cb0f58fb02b1f54f9e86522d2f918 upstream.

As there is no threaded handler, replace devm_request_threaded_irq()
with devm_request_irq(), and as the handler calls iio_trigger_poll()
which may not be called from a threaded handler replace IRQF_ONESHOT
with IRQF_NO_THREAD.

Since commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT
without a threaded handler"), the IRQ core checks IRQF_ONESHOT flag
in IRQ request and gives a warning if there is no threaded handler.
