[PATCH] PCI: cleanup unused variable about msi driver
In IA64 platform, msi driver does not use irq_vector variable, and in x86 platform LAST_DEVICE_VECTOR should one before FIRST_SYSTEM_VECTOR, this patch modify this. Signed-off-by: bibo, mao <bibo.mao@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
