[PATCH] zd1211rw: Allow channels 1-13 in Japan
Eric Goff found that he could not use his ZD1211 device which is programmed for the Japan regulatory domain. It turns out that ZyDAS deviate from the spec here: they do not use the newer Japan region code (0x41) but their drivers do operate as if the newer Japan legal frequency range is in effect.
