mfd: wm8350-core: Use IRQF_ONESHOT

2026-03-04T12:19:39+00:00

[ Upstream commit 553b4999cbe231b5011cb8db05a3092dec168aca ] 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.
