Hi Kai-Heng,
> Realtek bluetooth may not work after reboot:

> This is a regression introduced by commit 26503ad25de8 ("Bluetooth:

> logic errors out early when no matching IC info can be found, in this
> case it means the firmware is already loaded.

> So let's assume the firmware is already loaded when we can't find
> matching IC info, like the old logic did.
