From: Jorgen Hansen <redacted> commit 8566b86ab9f0f45bc6f7dd422b21de9d0cf5415a upstream. The recent fix for the vsock sock_put issue used the wrong initializer for the transport spin_lock causing an issue when running with lockdep checking. Testing: Verified fix on kernel with lockdep enabled. Reviewed-by: Thomas Hellstrom <redacted> Signed-off-by: Jorgen Hansen <redacted> Signed-off-by: David S.
