Subject: ath9k_hw: Fix selfgen chainmask for 9565
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7d47884f306afd1d0215133685f451aaafe3ca7a;p=linux-beck.git

ath9k_hw: Fix selfgen chainmask for 9565

Self generated MCI messages is configured to use chain 1. As
ar9565 is 1x1 solution, It can not use Chain 1. Hence fix
Chain 1 for ar9462 alone. Not doing so, could affect WLAN
connectivity in ar9565 as LNA sharing is not informed by BT.
