Subject: r8169: simplify rtl8169_alloc_rx_data
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d3b404c29c97ecf56001dc94f94a5b8e5efcd2e3;p=openwrt%2Fstaging%2Fblogic.git

r8169: simplify rtl8169_alloc_rx_data

dev->dev.parent has the same value as tp_to_dev(tp)
(set by SET_NETDEV_DEV() in rtl_init_one()) and we know it can't be NULL.
This allows us to simplify the code.
