From: Karthikeyan Periyasamy <[email protected]>
When hardware device group abstraction is introduced, QMI firmware
ready event of different devices in a group can be received simultaneously.
To indicate firmware ready event is completed for a particular device in a
group set a flag (ATH12K_FLAG_QMI_FW_READY_COMPLETE). This would be
helpful when hardware recovery is introduced for hardware device group
abstraction.
Add changes to set/unset ATH12K_FLAG_QMI_FW_READY_COMPLETE flag for a
device.
