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-&gt;auxr_dev = NULL and frees the underlying object. The subsequent<br /> bd-&gt;auxr_dev-&gt;net = bd-&gt;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...)
