From 3e034797191de9981cddff4d1a8203d020360958 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 22 Apr 2013 12:33:53 -0700 Subject: [PATCH] staging: comedi: ni_labpc: pass the isr_flags to labpc_common_attach() The PCI and PCMCIA LabPC boards use shared interrupts and need the IRQF_SHARED flag set when requesting the irq, the ISA boards do not. Instead of checking the 'bustype' in labpc_common_attach() in order to determine the isr_flags, just pass the flags as a parameter to the function.
