[PATCH v2 02/20] platform/x86: int0002: Remove IRQF_ONESHOT from request_irq()

[Sebastian Andrzej Siewior]

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 flag was added to match the flag on the shared handler which uses a
threaded handler and therefore IRQF_ONESHOT. This is no longer needed
because devm_request_irq() now passes IRQF_COND_ONESHOT for this case.

Revert adding IRQF_ONESHOT to irqflags.
