[PATCH v2 7/8] tty: serial: qcom_geni_serial: Return IRQ_NONE for spurious interrupts

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

 



Currently the driver returns IRQ_HANDLED when spurious interrupts happen.
This is misleading. Fix the behavior by returning IRQ_NONE for spurious
interrupts.
