From: Felix Fietkau Date: Wed, 22 Oct 2014 16:17:35 +0000 (+0200) Subject: ath9k_common: always update value in ath9k_cmn_update_txpow X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=763254516187015cb5b391553af35c6ed1f4bb36;p=openwrt%2Fstaging%2Fblogic.git ath9k_common: always update value in ath9k_cmn_update_txpow In some cases the limit may be the same as reg->power_limit, but the actual value that the hardware uses is not up to date. In that case, a wrong value for current tx power is tracked internally. Fix this by unconditionally updating it. Signed-off-by: Felix Fietkau Signed-off-by: John W.
