Return-path: Received: from cavan.codon.org.uk ([93.93.128.6]:57491 "EHLO cavan.codon.org.uk" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1758557AbZKKThO (ORCPT ); Wed, 11 Nov 2009 14:37:14 -0500 From: Matthew Garrett To: linux-wireless@vger.kernel.org Cc: linville@tuxdriver.com, Matthew Garrett Subject: [PATCH 1/2] ipw2100: Register the wiphy device Date: Wed, 11 Nov 2009 14:36:30 -0500 Message-Id: <1257968191-495-1-git-send-email-mjg@redhat.com> Sender: linux-wireless-owner@vger.kernel.org List-ID: libipw unconditionally calls wiphy_unregister, but it's up to the driver to register it in the first place. ipw2100 fails to do so. Add the necessary glue code, and also ensure that rfkill statuses get set up appropriately.
