Subject: Input: elantech - allow forcing Elantech protocol
From: Florian Ragwitz <[email protected]>
commit f81bc788ff91d4efd4baf88b2c29713838caa8e5 upstream.
Apparently hardware vendors now ship elantech touchpads with different version
magic. This options allows for them to be tested easier with the current driver
in order to add their magic to the whitelist later.
