Subject: [06/90] ath5k: allow setting txpower to 0
2.6.31-stable review patch. If anyone has any objections, please let us know.
------------------
From: Bob Copeland <me@...copeland.com>
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
