Subject: iwlwifi: fix TX power antenna access
From: Johannes Berg <[email protected]>
commit a5fdde28b4f5fb756032e7ad2c6fcdcffde20958 upstream.
Since my commit
iwlwifi: use valid TX/RX antenna from hw_params
the config values are pure overrides, not the
real values for all hardware. Therefore, the
EEPROM TX power reading code checks the wrong
values, it should check the hw_params values.
