From 6b1968d5b6e223237bca98879f31c5616b3b325f Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Fri, 9 Mar 2012 13:55:43 +0100 Subject: [PATCH] HID: make it possible to force hid-core claim the device Introduce 'hid_ignore_special_drivers' module parameter that makes hid-core claim the device even if it's listed in hid_have_special_driver[]. This is useful mostly for debugging purposes and specialized initrds, where all the hid drivers are not avaiable.
