Hi Jia-Ju,

[FUNC] schedule_timeout

Here, mwifiex_send_cmd does not call mwifiex_wait_queue_complete, because the sync parameter is false.
Note that the function mwifiex_multi_chan_resync did call mwifiex_send_cmd with sync = false.

Thanks for the reply.
I check the code again, and find my report it false, sorry for that.

Best wishes,
