Subject: zd1201: replace function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan}

X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3d54b9052c08a473f56cbed6a0bb4c900c948474;p=platform%2Fkernel%2Flinux-arm64.git

zd1201: replace function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan}

Replace ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} with more
generic ieee80211_{channel_to_frequency, frequency_to_channel}.

Function ieee80211_frequency_to_channel() will return 0 if frequency
is not correctly provided, so no need to set channel to 0 explicitly.

Include <net/cfg80211.h> for the defination of IEEE80211_BAND_2GHZ.
Because <net/cfg80211.h> includes <linux/ieee80211.h>, so we can
replace <linux/ieee80211.h> with <net/cfg80211.h>.

This change is a preparation for the removal of function
ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan}.
