Subject[PATCH] e1000e: free IRQ when the link is up or down
Date
Move IRQ free code so that it will happen regardless of the
link state. Currently the e1000e driver only releases its IRQ
if the link is up. This is not sufficient because it is
possible for a link to go down without releasing the IRQ. A
secondary bus reset can cause this case to happen.
