From 7b2809efb16e4a975666b9b14f3e37edd4b39ad2 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Thu, 31 Jul 2014 14:47:50 +0100 Subject: [PATCH] staging: comedi: amplc_pci224: remove "legacy" attach mechanism Since the driver no longer supports options in its "legacy" attach mechanism to describe the jumper settings (or any options beyond restricting a PCI search to a particular bus and/or slot), there is no need to retain this mechanism in the driver. Remove the comedi driver "attach" handler `pci224_attach()`, and the now unused `pci224_find_pci_dev()`. Also, remove the "wildcard" entry from the board table `pci224_boards[]` as it is no longer needed.
