From c612d5a20e2ebb2a03404a9d81c0383bba096a79 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Wed, 4 Feb 2009 11:23:56 -0700 Subject: [PATCH] powerpc/5200: Don't specify IRQF_SHARED in PSC UART driver commit d9f0c5f9bc74f16d0ea0f6c518b209e48783a796 upstream. 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.
