From f9f788f0721350e594ce3e7978968847b057afc1 Mon Sep 17 00:00:00 2001 From: Simon Glass <sjg@chromium.org> Date: Thu, 26 Mar 2015 09:29:41 -0600 Subject: [PATCH] i8042: Add keyboard enable logic in kbd_reset() This code appears to be missing a piece that is needed on some keyboards to enable the keyboard. Add this in. This makes the keyboard work correctly on chromebook_link.
