Subject: iwlwifi: removing IWL4965_HT config
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4f85f5b39208e755a93f63296ec1224d14121b6c;p=linux-beck.git

iwlwifi: removing IWL4965_HT config

This patch removes CONFIG_IWL4965_HT #ifdefs for iwl 4965 and 5000. 11n
feature is stable in those drivers and its mode of operation is determined
in mac80211, so this dependency is not needed any more.
