From: Ulrik De Bie Date: Fri, 14 Nov 2014 01:47:04 +0000 (-0800) Subject: Input: elantech - provide a sysfs knob for crc_enabled X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2d9eb81fdb9f08df3a4b1638c1270a4453b40ac2;p=linux-beck.git Input: elantech - provide a sysfs knob for crc_enabled 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).
