[PATCH v3 09/12] Input: wm831x-ts - request_irq by IRQF_NO_AUTOEN and remove disable_irq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable because of requesting.
