From 35f2c7c0ce8eb09d19fb50ed2cd29b6dbea9cd86 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Wed, 22 Nov 2006 00:06:32 +0000 Subject: [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.
