Subject: [PATCH 4.14 29/52] platform/chrome: cros_ec_lpc: remove redundant pointer request

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

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

commit d3b56c566d4ba8cae688baf3cca94425d57ea783 upstream.

Pointer request is being assigned but never used, so remove it. Cleans
up the clang warning:

drivers/platform/chrome/cros_ec_lpc.c:68:2: warning: Value stored to
'request' is never read
