[PATCH 4.4 38/41] xen/netback: fix error path of xenvif_connect_data()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Juergen Gross <jgross@xxxxxxxx>

commit 3d5c1a037d37392a6859afbde49be5ba6a70a6b3 upstream.

xenvif_connect_data() calls module_put() in case of error. This is
wrong as there is no related module_get().

Remove the superfluous module_put().

Fixes: 279f438e36c0a7 ("xen-netback: Don't destroy the netdev until the vif is shut down")
