The construct 'freq_start-10, freq_end+10' is consistent with other drivers e.g.

drivers/net/wireless/mac80211_hwsim.c
drivers/net/wireless/broadcom/brcm80211/brcmsmac/channel.c:#define
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c
drivers/net/wireless/realtek/rtlwifi/regd.c
drivers/net/wireless/ath/regd.c

and looks better (to me) without the inserted spaces.

If the change is required will the other drivers be 'corrected'?
