[024/151] ath5k: allow setting txpower to 0

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Bob Copeland <me@xxxxxxxxxxxxxxx>

commit 2eb2fa67e5462a36e98172fb92c78bc405b3035f upstream.

As a holdover from earlier code when we used to set
the power limit to '0' after a reset to configure the
default transmit power, ath5k interprets txpower=0 as
12.5 dBm.  Fix that by just passing 0 through.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14567
