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.
