From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Currently there is an error return path that neglects to free the allocation for lcb_context. Fix this by adding a new error free exit path that kfree's lcb_context before returning. Use this new kfree exit path in another exit error path that also kfree's the same object, allowing a line of code to be removed.
