Subject: [PATCH] input: elantech: remove redundant assignments to variable error

From: Colin Ian King <colin.king@...onical.com>

The variable error is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
