[OpenWrt-Devel] [PATCH] [packages] mac80211: remove extra list_del on 3.14 kernels after 3.14.8

[Mark Milburn]

As of 3.14.9 unregister_netdevice_many() in net/core/dev.c includes a
 list_del().  This means that any code that calls ieee80211_remove_interfaces()
 will oops when using 3.14 kernels newer than 3.14.9.  Check that kernel 
 version is not a 3.14.x newer than 3.14.8 before adding list_del() in
 ieee80211_remove_interfaces().  Fixes rmmod for mwl8k.

Mark Milburn (1):
  Protect 3.14.9 and higher 3.14 kernels from extra list_del
