From da3d50ef308d53f216f1f92f4971f245c13e9f65 Mon Sep 17 00:00:00 2001 From: Sven Schmitt Date: Thu, 9 Aug 2012 14:46:34 +0200 Subject: [PATCH] can: sja1000_platform: fix wrong flag IRQF_SHARED for interrupt sharing The sja1000 platform driver wrongly assumes that a shared IRQ is indicated with the IRQF_SHARED flag in irq resource flags. This patch changes the driver to handle the correct flag IORESOURCE_IRQ_SHAREABLE instead. There are no mainline users of the platform driver which wrongly make use of IRQF_SHARED.
