The original patch 60789afc02f592b8d91217b60930e7a76271ae07
("Bluetooth: Shutdown controller after workqueues are flushed or
cancelled") is causing the tx fail when downloading fw on mediatek
mt8183 device using QCA bluetooth:

Want to know if reverting 60789afc02f59 is a cure.

Reverting 60789afc02f592b8d91217b60930e7a76271ae07 can also fixed the issue.

After applying the fixup to allow tx, the issue is solved.

Feel free to specify the fixup and its link to 60789afc02f59.
