Subject: [PATCH] thunderbolt: Use the actual buffer in tb_async_error()
Git-commit: eb100b8fa8e8b59eb3e5fc7a5fd4a1e3c5950f64
Patch-mainline: v6.0-rc4
References: git-fixes

The received notification packet is held in pkg->buffer and not in pkg
itself. Fix this by using the correct buffer.

Fixes: 81a54b5e1986 ("thunderbolt: Let the connection manager handle all notifications")
