I don't know what it is, but looks like a race condition / memory corruption somewhere. I just saw the issue as well, but I had to run the test suite a few times as I got some clean runs in as well. I must have been luckily to have submitted on a clean run.

What the heck. It is something devres related on cleanup. I disabled some code paths in the driver (e.g. storing devices in a list and player id) and then the issue jumps around to then power_supply_unregister as called by devres. At least I'm glad this issue surfaces now, but I'm not yet sure where to search. I find it is so weird that Bluetooth patch shows this. USB is fine and the changes do look fairly straight-forward with nothing obviously sticking out yet... Roderick

Bluetooth needs a bigger buffer (78 vs 32 bytes), so some data must have gotten overwritten elsewhere. How should I submit this change?

Add support for DualShock4 in Bluetooth mode. In Bluetooth, the device is a bit strange in that after 'calibration' it switches sending all its input data from a basic report (only containing buttons/sticks) to an extended report, which also contains touchpad, motion sensors and other data. The overall design of this code is similar to the DualSense code.
