nfc: netlink: fix double device reference drop
The function nfc_put_device(dev) is called twice to drop the reference to dev when there is no associated local llcp. Remove one of them to fix the bug. Fixes: 52feb444a903 ("NFC: Extend netlink interface for LTO, RW, and MIUX parameters support") Fixes: d9b8d8e19b07 ("NFC: llcp: Service Name Lookup netlink interface") Signed-off-by: Pan Bian <bianpan2016@163.com> Reviewed-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S.
