ath9k: Initialize MCI state correctly
The MCI configuration values are assigned in ath9k_hw_btcoex_init_mci() which are used by the MCI reset routine. When initializing BTCOEX/MCI, ath_mci_setup() ends up using uninitialized data. Fix this by setting up the configuration parameters before issuing a MCI reset. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
