From 786e3dfbae8e2da422affcc1736ca1888f200a27 Mon Sep 17 00:00:00 2001 From: Bjorge Dijkstra Date: Sat, 26 Jan 2008 00:50:44 +0200 Subject: [PATCH] cdc_ether: Hardwire CDC descriptors when missing Just as ActiveSync devices, some regular RNDIS devices also lack the CDC descriptors (e.g. devices based on BCM4320 WLAN chip). This patch hardwires the CDC descriptors for all RNDIS style devices when they are missing.
