Subject: [PATCH] powerpc: 85xx: EDAC PCI: request irq as IRQF_SHARED
Date: Mon, 20 Jan 2014 16:56:15 +0800 [thread overview]
Message-ID: <1390208175-3656-1-git-send-email-tiejun.chen@windriver.com> (raw)
AER driver needs to share this PCI err irq with EDAC, otherwise
we can't register AER driver successfully as follows:
genirq: Flags mismatch irq 482. 00000080 (aerdrv) vs. 00000020 ([EDAC] PCI err)
CPU: 3 PID: 1 Comm: swapper/0 Not tainted 3.13.0-rc1-148346-g2513817 #69
