From: Florian Ragwitz Date: Tue, 27 Apr 2010 07:47:04 +0000 (-0700) Subject: Input: elantech - allow forcing Elantech protocol X-Git-Tag: v2.6.34-rc7~22^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f81bc788ff91d4efd4baf88b2c29713838caa8e5;p=profile%2Fivi%2Fkernel-x86-ivi.git Input: elantech - allow forcing Elantech protocol 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.
