From: Bob Copeland Date: Mon, 16 Nov 2009 13:30:29 +0000 (-0500) Subject: ath5k: allow setting txpower to 0 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2eb2fa67e5462a36e98172fb92c78bc405b3035f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ath5k: allow setting txpower to 0 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.
