From 49445b9117a6e9ca9a741251784432a1da2f9919 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 8 Nov 2013 15:03:41 +0000 Subject: [PATCH] staging: comedi: remove comedi_dev_from_minor() The `comedi_dev_from_minor()` function is no longer used, so remove it. Calls to it have either been replaced by calls to `comedi_dev_get_from_minor()` or by using the `private_data` member of the open file object.
