RE: [EXT] [BUG] net: wireless: mwifiex: A possible sleep-in-atomic-context bug in mwifiex_wait_queue_complete()

Hi Jia-Ju,

[FUNC] schedule_timeout
drivers/net/wireless/marvell/mwifiex/sta_ioctl.c, 63:
     schedule_timeout in mwifiex_wait_queue_complete
drivers/net/wireless/marvell/mwifiex/cmdevt.c, 673:
     mwifiex_wait_queue_complete in mwifiex_send_cmd

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.

drivers/net/wireless/marvell/mwifiex/main.c, 1046:
     mwifiex_send_cmd in mwifiex_multi_chan_resync
drivers/net/wireless/marvell/mwifiex/usb.c, 288:
     mwifiex_multi_chan_resync in mwifiex_usb_tx_complete

Thanks,
Ganapathi
