From: Zhao, Gang Date: Tue, 18 Feb 2014 13:36:03 +0000 (+0800) Subject: ieee80211: remove function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} X-Git-Tag: firefly_0821_release~176^2~4167^2~18^2^2~226 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3ebe8e257307a87c33460aa7d2b75dadd374ed9c;p=firefly-linux-kernel-4.4.55.git ieee80211: remove function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} Function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} have been replaced with ieee80211_{channel_to_frequency, frequency_to_channel}. There should be no users of the two functions now. So remove them. Cc: Johannes Berg Signed-off-by: Zhao, Gang Signed-off-by: John W.
