When the\n3rd argument buf doesn't match with \"offline\", \"online\" or \"remove\", the\nfunction simply returns -EINVAL and forgets to decrease the reference\ncount of a rpc_xprt object and a rpc_xprt_switch object increased by\nrpc_sysfs_xprt_kobj_get_xprt() and\nrpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of\nboth unused objects.\n\nFix this issue by jumping to the error handling path labelled with\nout_put when buf matches none of \"offline\", \"online\" or \"remove\"."

Cuando el tercer argumento buf no coincide con \"fuera de l\u00ednea\", \"en l\u00ednea\" o \"eliminar\", la funci\u00f3n simplemente devuelve -EINVAL y se olvida de disminuir el recuento de referencias de un objeto rpc_xprt y un objeto rpc_xprt_switch aumentado en rpc_sysfs_xprt_kobj_get_xprt() y rpc_sysfs_xprt_kobj_get_xprt_switch (), lo que provoca fugas en el recuento de referencias de ambos objetos no utilizados.
