4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King colin.king@canonical.com
commit 531beb067c6185aceabfdee0965234c6a8fd133b upstream.
sg_table is being initialized and is never read before it is updated again later on, hence making the initialization redundant. Remove the initialization.
Detected by clang scan-build: "warning: Value stored to 'sg_table' during its initialization is never read"
