From 7d8a25674f8358e09daf4f1ed4e7dd93416f7b5b Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 19 Dec 2012 15:38:53 -0700 Subject: [PATCH] staging: comedi: comedi_fops: rename comedi_{read,write}_subdevice() The 'get' usually implies increasing a reference count of an object. These function return a pointer but do not do any reference counting. For aesthetic reasons, rename the functions to better represent what they do.
