wifi: ath12k: Add lock to protect the hardware state

Browse source

Currently, hardware state is not protected across the reconfigure
operations. However, in single wiphy models, multiple radio/links is
exposed as a MAC hardware (ieee80211_hw) through the driver hardware
abstraction (ath12k_hw) layer. In such scenario, we need to protect
hardware state across the multiple radio/link at the driver hardware
abstraction (ath12k_hw) layer. Therefore, introduce a new mutex in
the ath12k_hw layer.
