snd_mpu401_uart_interrupt - generic MPU401-UART interrupt handler : the irq number : mpu401 instance

snd_mpu401_uart_new - create an MPU401-UART instance : the card instance : the device index, zero-based : the hardware type, MPU401_HW_XXXX : the base address of MPU401 port : bitflags MPU401_INFO_XXX : the ISA irq number, -1 if not to be allocated : the pointer to store the new rawmidi instance
Creates a new MPU-401 instance.
Note that the rawmidi instance is returned on the rrawmidi argument, not the mpu401 instance itself. To access to the mpu401 instance, cast from rawmidi->private_data (with struct snd_mpu401 magic-cast).
Returns zero if successful, or a negative error code.
