From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ulrik De Bie Subject: [PATCH v2 2/3] Input: elantech - provide a sysfs knob for crc_enabled Date: Sun, 9 Nov 2014 22:38:36 +0100 Message-ID: <1415569117-29461-3-git-send-email-ulrik.debie-os@e2big.org> References: <1415569117-29461-1-git-send-email-ulrik.debie-os@e2big.org> Return-path: Received: from e2big.org ([198.61.226.133]:41429 "EHLO e2big.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751439AbaKIVjK (ORCPT ); Sun, 9 Nov 2014 16:39:10 -0500 In-Reply-To: <1415569117-29461-1-git-send-email-ulrik.debie-os@e2big.org> Sender: linux-input-owner@vger.kernel.org List-Id: linux-input@vger.kernel.org To: Dmitry Torokhov Cc: linux-input@vger.kernel.org, Hans de Goede , David Herrmann , ulrik.debie-os@e2big.org The detection of crc_enabled is known to fail for Fujitsu H730. A DMI blacklist is added for that, but it can be expected that other laptops will pop up with this. Here a sysfs knob is provided to alter the behaviour of crc_enabled. Writing 0 or 1 to it sets the variable to 0 or 1. Reading it will show the crc_enabled variable (0 or 1).
