iio: magnetometer: Remove IRQF_ONESHOT
[ Upstream commit a54e9440925e6617c98669066b4753c4cdcea8a0 ]
Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also disallows force-threading of the primary handler and the
irq-core will warn about this.
The force-threading functionality is required on PREEMPT_RT because the
handler is using locks with can sleep on PREEMPT_RT.
Remove IRQF_ONESHOT from irqflags.
