And I would really prefer if this gets changed to use a workqueue instead of a timer.

I am really not doing this. You need to stop doing this SoC X or SoC Y crap. I said this before and I am saying this again, start from scratch and write a clean serdev only driver. Adding things to hci_qca is just a hack.

[Harish]: The full implementation of IBS is based on timers
to that reason I have switched to timers.
