Subject: b43: N-PHY: add RF power tables for radio 0x2057 revs 9 & 14
X-Git-Tag: firefly_0821_release~176^2~3043^2~133^2~79
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a68c356bcf1e76ae649e929db5e4cea9e6bdcd65;p=firefly-linux-kernel-4.4.55.git
b43: N-PHY: add RF power tables for radio 0x2057 revs 9 & 14
Don't write them as we don't have gains configured correctly yet.
