From 226ee6751541a958cd1ad982f5ba0f9affde6141 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Mon, 29 Sep 2014 11:55:34 +0200 Subject: ARCNET: return IRQ_NONE if the interface isn't running The interrupt handler needs to return IRQ_NONE in case two devices are used with the shared interrupt handler. Otherwise it could steal interrupts from the other interface. Signed-off-by: Michael Grzeschik Signed-off-by: David S.
