From: Dmitry Torokhov Date: Wed, 5 Sep 2007 03:46:42 +0000 (-0400) Subject: Input: remove ec3104_keyb driver X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b9198c3239a661c468c0f6340c21919b7dd0012f;p=linux-beck.git Input: remove ec3104_keyb driver Now that ec3104 board support has been removed nothing references this driver so it can be safely removed as well.
