- Subject: [PATCH] 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.
