Sebastian Andrzej Siewior 553b4999cb mfd: wm8350-core: Use IRQF_ONESHOT 
Using a threaded interrupt without a dedicated primary handler mandates
the IRQF_ONESHOT flag to mask the interrupt source while the threaded
handler is active. Otherwise the interrupt can fire again before the
threaded handler had a chance to run.

Mark explained that this should not happen with this hardware since it
is a slow irqchip which is behind an I2C/ SPI bus but the IRQ-core will
refuse to accept such a handler.

Set IRQF_ONESHOT so the interrupt source is masked until the secondary
handler is done.

Fixes: 1c6c69525b ("genirq: Reject bogus threaded irq requests")
