Subject: [PATCH] staging: vc04_services: remove redundant assignment to pointer service

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

Pointer service is being set to NULL however this value is never
read and so the assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
