NAK.  Seriously. Don't resend this.  NAK.

That string DOES get used later, like when you cat /proc/interrupts.
So you can't allocate it on the stack.  It's got to be persistent,
just like we have it.  Heck, look at the declaration for
request_irq().  The devname param is declared as const char *.

So NAK.  Same for igb and ixgbe.  Don't do this.
