From f3abc831386e3606fbb21acf0ee5231df0d0185f Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Thu, 4 Apr 2013 14:59:12 +0100 Subject: [PATCH] staging: comedi: refactor comedi_dev_from_minor() Refactor `comedi_dev_from_minor()` to call one of two new functions `comedi_dev_from_board_minor()` (for minor device numbers less than `COMEDI_NUM_BOARD_MINORS`) or `comedi_dev_from_subdevice_minor()` (for minor device numbers greater than or equal to `COMEDI_NUM_BOARD_MINORS`, which are subdevice minor device numbers). Remove `comedi_file_info_from_minor()` as it is no longer used. This is a step towards removing `struct comedi_file_info`.
