From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christopher Heiny Subject: [PATCH] input synaptics-rmi4: Debugfs initialization fixes Date: Tue, 10 Dec 2013 18:12:04 -0800 Message-ID: <1386727924-11522-1-git-send-email-cheiny@synaptics.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Received: from us-mx2.synaptics.com ([192.147.44.131]:3328 "EHLO us-mx2.synaptics.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750806Ab3LKCMK (ORCPT ); Tue, 10 Dec 2013 21:12:10 -0500 Sender: linux-input-owner@vger.kernel.org List-Id: linux-input@vger.kernel.org To: Dmitry Torokhov Cc: Linux Input , Christopher Heiny , Andrew Duggan , Vincent Huang , Vivian Ly , Daniel Rosenberg , Jean Delvare , Joerie de Gram , Linus Walleij , Benjamin Tissoires This fixes the broken #ifdefs on CONFIG_RMI4_DEBUG. Per device debugfs setup is reordered to ensure that the debugfs tree for a given device is created before it is registered (since the action of registering a device may cause other things to happen that depend on debugfs being initialized already).
