Just for me, the rename/refactor happened in commit fa0ecbb9905d
("mwifiex: remove global variable cmd_wait_q_required"), in v3.14.

What about the code path from mwifiex_add_card()?
mwifiex_add_card()
-> hw_status = MWIFIEX_HW_STATUS_INITIALIZING
-> mwifiex_init_hw_fw(adapter, true))
-> request_firmware_nowait(..., mwifiex_fw_dpc)
mwifiex_fw_dpc()
...
-> mwifiex_init_fw()
-> adapter->hw_status = MWIFIEX_HW_STATUS_READY
mwifiex_fw_dpc() is called asynchronously, is everything as safe as
before, here?
