Subject: lantiq: drop obsolete patch
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c0e66478b520b07c33343161f722351f5f858990;p=openwrt%2Fstaging%2Fansuel.git

lantiq: drop obsolete patch

ifxhcd never had roothub support but since kernel 3.x it was expected
that a roothub always exists.

The patched fixed a null pointer deref in the usb subsystem because of
the missing roothub.

Since ifxhcd is gone, this whole patch isn't required any longer.
