4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Colin Ian King <[email protected]> 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.
