hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer
commit e629295bd60abf4da1db85b82819ca6a4f6c1e79 upstream. When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL. Signed-off-by: Hyunwoo Kim <v4bel@theori.io> Reviewed-by: Stefano Garzarella <sgarzare@redhat.com> Acked-by: Michael S.
