From 9718e5dfd7e19a2fb0d98a9afdb0459ba6b5d41f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 22 Mar 2013 09:47:20 -0700 Subject: [PATCH] staging: comedi: ni_labpc: remove unnecessary test of dev->irq The ai subdevice (*do_cmd) pointer is only initialized if the driver has successfully requested the interrupt. The extra test in labpc_ai_cmd() is not necessary.
