From: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx> Currently MAC HW un/register helper function support the single radio. To enable single/multi link operation in the future, the following helper functions need to be refactored to accommodate multiple radios under a single MAC HW un/register: * ath12k_ah_to_ar() * ath12k_mac_hw_allocate() * ath12k_mac_hw_register() * ath12k_mac_hw_unregister() This refactoring will make it easier to scale these functionalities and support Multi link operation.
