[PATCH 2/2] tty/8250 Add XR17D15x devices to the exar_handle_irq override

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

 



Add XR17D15x devices to the exar_handle_irq override: they have the
same extra interrupt register that could fire and never be serviced by
the standard handle_irq.
