Hi,
This series cleans up the BTCOEX MCI states and
introduces utility functions for MCI GPM offset.
Rajkumar Manoharan (8):
ath9k_hw: cleanup MCI gpm offset state
ath9k_hw: add utility function to set BT version
ath9k_hw: remove MCI_STATE_SEND_WLAN_CHANNELS
ath9k_hw: remove MCI_STATE_NEED_FLUSH_BT_INFO
ath9k_hw: remove p_data argument from ar9003_mci_state
ath9k_hw: remove MCI_STATE_BT
ath9k_hw: remove MCI_STATE_CONT_* state
ath9k_hw: remove MCI_STATE_SET_BT_SLEEP
