CS4236+ driver Background: The card/chipset supports an external MIDI interrupt. By default, this interrupt isn't used (because the isapnp mechanism chooses a configuration without an assigned interrupt). If the user wishes to explicitly select an interrupt via the mpu_irq parameter for such a configured device, it doesn't work: The driver always shows: isapnp MPU: port=0x330, irq=-1 (note the 'irq=-1') Problem: The driver only allows to set the irq if pnp_irq_valid returns true for this particular pnp device. This, however, is only true if an interrupt has already been assigned (pnp_valid_irq returns true if the flag IORESOURCE_IRQ is set and IORESOURCE_UNSET is not set). If no interrupt has been assigned so far, IORESOURCE_UNSET is set and pnp_irq_valid returns false, thereby inhibiting the selection of a valid irq. Solution: Don't check for a valid (= already assigned) irq at the point of calling pnp_resource_change. Tested successfully on Linux 2.6.11.
