The Addi-Data PCI drivers for Comedi use sprintf() in their comedi
"attach" routine to construct a string to pass as the name in the call
to request_irq(). All calls to "attach" routine share the same static
buffer for this name, but the contents will differ on each call
(including the comedi device number and the comedi board name). This
changes the name displayed in /proc/interrupts for previous calls to
request_irq() using the same buffer. Just use the board name instead;
it has slightly less information (no comedi device number) but at least
it doesn't change over the lifetime of the IRQ handler.
