card->adapter gets initialized in mwifiex_register_dev(). As it's not cleared in mwifiex_unregister_dev(), we may end up accessing the memory which is already free in below scenario. Scenario: Driver initialization is failed due to incorrect firmware or some other reason. Meanwhile device reboot/unload occurs. This is safe, now that we've properly synchronized suspend() and remove() with the FW initialization thread; now that code can simply check for 'card->adapter == NULL' and exit safely.
