regression: kernel 6.4.x breaks scanning/pairing (but not use) of LE devices

[Bruno Pitrus <brunopitrus@xxxxxxxxxxx>]

I am using openSUSE Tumbleweed on a Dell Precision 3551 which has a bluetooth adapter of ID 8087:0026 (Intel AX201).
I am using a Logitech M575 trackball mouse which only supports Bluetooth LE.

With kernel 6.4.2 or newer, scanning for devices — using either the KDE gui or bluetoothctl — most of the time returns only “classic bluetooth” devices like computers and phones, and not the mouse.
If the mouse was paired before, it works correctly however.

With previous kernel versions (6.3.9 and before), pairing the mouse worked correctly.
