[PATCH] iio: adc: ti-ads1119: Replace IRQF_ONESHOT with IRQF_NO_THREAD

[Felix Gu]

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.

Since there is no threaded handler, replace devm_request_threaded_irq
with devm_request_irq, and replace IRQF_ONESHOT with IRQF_NO_THREAD.

Fixes: a9306887eba4 ("iio: adc: ti-ads1119: Add driver")

Although I would swap the order of paragraphs in the commit
message. The second one is the real problem (so should go first)
and the first one is just how the problem was found.

I rewrote the commit message along those lines and called
out why it needs IRQF_NO_THREAD.

Applied to the fixes-togreg branch of iio.git and marked for stable.

Given proximity to the patch removing the message, it may be this
will cause some slight mess in linux-next.

Thanks,

Jonathan

Also consider dropping this duplicate message as the callee does it already.
