From: Sathishkumar Muruganandam <quic_murugana@xxxxxxxxxxx> Currently, when the vdev start WMI cmd is sent from host, vdev related parameters such as max_reg_power, max_power, and max_antenna_gain are multiplied by 2 before being sent to the firmware. This is incorrect because the firmware uses 1 dBm steps for power calculations. This leads to incorrect power values being used in the firmware and radio, potentially causing incorrect behavior. Fix the update of max_reg_power, max_power, and max_antenna_gain values in the ath12k_mac_vdev_start_restart function, ensuring accurate power settings in the firmware by sending these values as-is, without multiplication.
