Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
bnge: return after auxiliary_device_uninit() in error path<br />
<br />
When auxiliary_device_add() fails, the error block calls<br />
auxiliary_device_uninit() but does not return. The uninit drops the<br />
last reference and synchronously runs bnge_aux_dev_release(), which sets<br />
bd->auxr_dev = NULL and frees the underlying object. The subsequent<br />
bd->auxr_dev->net = bd->netdev then dereferences NULL, which is not a<br />
good thing to have happen when trying to clean up from an error.<br />
<br />
Add the missing return, as the auxiliary bus documentation states is a<br />
requirement (seems that LLM tools read documentation better than humans<br />
do...)
