From 72f4202f1ff20edfcc34368488d5bd760fac57b6 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 24 Jul 2014 10:14:35 -0700 Subject: [PATCH] staging: comedi: ni_tio: convert NI_660x_Gate_Pin_Gate_Select() to a macro The BUG_ON() in this function can never happen. For aesthetics, rename this CamelCase inline function and convert it into a simple macro.
