Subject: [PATCH] staging: comedi: addi_apci_1564: move apci1564_interrupt()
 into addi_apci_1564.c

On moving the function into the driver proper, also check the device is
asserting the shared interrupt line.

This patch also fixes the interrupt handling for the digital input
change-of-state interrupts.
