From: Grant Likely Date: Wed, 4 Feb 2009 18:23:56 +0000 (-0700) Subject: powerpc/5200: Don't specify IRQF_SHARED in PSC UART driver X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d9f0c5f9bc74f16d0ea0f6c518b209e48783a796;p=deliverable%2Flinux.git powerpc/5200: Don't specify IRQF_SHARED in PSC UART driver The MPC5200 PSC device is wired up to a dedicated interrupt line which is never shared. This patch removes the IRQF_SHARED flag from the request_irq() call which eliminates the "IRQF_DISABLED is not guaranteed on shared IRQs" warning message from the console output.
