Message-Id: <1411556523-28100-2-git-send-email-m.grzeschik@pengutronix.de> Date: Wed, 24 Sep 2014 13:01:59 +0200 From: Michael Grzeschik <m.grzeschik@...gutronix.de> To: netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, kernel@...gutronix.de Subject: [PATCH 1/5] 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.
