Bug description:
Bug 1928838 fixed possible kernel panic when doing rfkill block on
Intel Bluetooth controller. The fix was also upstreamed in v5.14-rc1
as commit 0ea9fd001a14e ("Bluetooth: Shutdown controller after
workqueues are flushed or cancelled") and was backported to v5.10.51,
v5.12.18, and v5.13.3. However, as indicated in
https://lore.kernel.org/linux-bluetooth/[email protected]/ ,
it caused a regression to mtkbtsdio and was then fixed in upstream
commit 0ea53674d07f (" Bluetooth: Move shutdown callback before
flushing tx and rx queue") since v5.15-rc1 and has been backported to
v5.14.3. Current statuses:
* v5.10.x:
* 0ea9fd001a14e: backported(v5.10.51), reverted(v5.10.57)
* 0ea53674d07f: backported(v5.10.65), reverted(v5.10.66)
* v5.11.x: N/A
* v5.12.x:
* 0ea9fd001a14e: backported(v5.12.18)
* v5.13.x:
* 0ea9fd001a14e: backported(v5.13.3), reverted(v5.13.9)
* 0ea53674d07f: backported(v5.13.17), reverted(v5.13.18)
* v5.14.x:
* 0ea9fd001a14e: committed(v5.14-rc1)
* 0ea53674d07f: backported(v5.14.3)

As a result, this affects 5.10/11/13 kernels.
