Revert eccc068e8e84c8fe997115629925e0422a98e4de which causes txpower to be stuck at 0.
Recent OpenWRT has txpower stuck at 0 for at least rt28xx, and I found this commit as the root cause: http://git.kernel.org/?p=linux/kernel/git/linville/wireless-next.git;a=commitdiff;h=eccc068e8e84c8fe997115629925e0422a98e4de Before reverting this "iw phy phy0 info" would show "0.0 dBm" as maximum transmit power for all frequencies. After reverting this (and with regdomain set to CH) it is back to the expected 20 dBm.
