Subject: lantiq: fix lantiq_mei.c and amazonse.dsti for adsl modem firmware
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ca2033d33f0c860e6c27bad0fc3937c6fbdae40;p=openwrt%2Fstaging%2Fluka.git

lantiq: fix lantiq_mei.c and amazonse.dsti for adsl modem firmware

The ltq-adsl-mei package is used for 3 lantiq device types:
danube, amazon-se and ar9.

These different SoC's need also different definitions.

Signed-off-by: Tino Reichardt <milky-lede@mcmilk.de>
[fix LTQ_USB_OC_INT for AR9 to match documentation]
