From: Serge Vasilugin <vasilugin@yandex.ru>

Support for the RT5350 WiSoC was added to OpenWrt after having a
lengthy debate about the legality of the original submission, see
https://lists.openwrt.org/pipermail/openwrt-devel/2013-January/018224.html
MTK/Ralink Acked replied and says we can merge this patch under the GPL.
