I was having issues with Bluetooth on the ASRock B850M with MT7925.
I tested this and other patches in my investigation process.
My issue was a platform bug causing a failure in USB enumeration
before the driver path (unrelated to the patch).

I can confirm this patch does not introduce regressions on this platform.
I tested system power cycling and suspension,
and also BT/Wifi adapter enable/disable.
Patch applied on top of mailine (7.2 rc1).

Tested-by: Rafael Passos <redacted>
Thanks a lot for your testing!

Your issue sounds related to the remote wakeup issue I am addressing. After triggering the remote wakeup bug, rebooting the platform without a power cycle [1] always causes a failure in USB enumeration before the driver path.

[1]: power off, unplug AC, wait for a while, plug AC, power on.

Thanks,
Rong
