Subject: staging: comedi: ni_labpc: pass the isr_flags to labpc_common_attach()
X-Git-Tag: upstream/snapshot3+hdmi~5290^2~30
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e034797191de9981cddff4d1a8203d020360958;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

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.
