4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Colin Ian King <[email protected]> [ Upstream commit 68d2059be660944152ba667e43c3b4ec225974bc ] Currently if map is null then a potential null pointer deference occurs when calling sock_release on map->sock. I believe the actual intention was to call sock_release on sock instead. Fix this.
