Subject: xen/netback: fix error path of xenvif_connect_data()
X-Git-Tag: v5.15~5278^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3d5c1a037d37392a6859afbde49be5ba6a70a6b3;p=platform%2Fkernel%2Flinux-starfive.git

xen/netback: fix error path of xenvif_connect_data()

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().
