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).
