Subject: [PATCH 3.4 027/177] rt2800: correct BBP1_TX_POWER_CTRL mask

From: Stanislaw Gruszka <sgruszka@...hat.com>

3.4.106-rc1 review patch.  If anyone has any objections, please let me know.

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


commit 01f7feeaf4528bec83798316b3c811701bac5d3e upstream.

Two bits control TX power on BBP_R1 register. Correct the mask,
otherwise we clear additional bit on BBP_R1 register, what can have
unknown, possible negative effect.
