Description

### Pre-flight checklist

- [x] I have searched existing issues and this is not a duplicate.
- [x] I have read the [Contributing Guidelines](https://github.com/CachyOS/linux-cachyos/blob/master/CONTRIBUTING.md).
- [x] I have verified the issue is reproducible with the latest available CachyOS kernel.
- [x] I have tried to reproduce the issue on Arch Linux's `linux` kernel.

### Upstream / vanilla kernel check

I have not tested with a vanilla/upstream kernel

### Kernel variant

linux-cachyos (EEVDF, Clang)

### System information (cachyos-bugreport.sh)

```text
Bug report was done on LTS Kernel, see additional information below:

https://paste.cachyos.org/p/6fe9d03.log
```

### Manual system information (if cachyos-bugreport.sh is unavailable)

```text

```

### Bug description

It took me a while to get the touchbar working and surviving a sleep/resume, which was accomplished by enabling mem_sleep_default=s2idle. This worked fine until 7.0.0, but with 7.0.1 the behaviour changed and the touchbar stays black after resuming.

### Steps to reproduce

1. use a Mac with T2 touchbar
2. use the same kernel options as me
3. do a fresh reboot: touchbar should work fine
4. go to sleep
5. turn the device back on by pressing the power button

### Expected behavior

Device should properly resume, the touchbar should turn on and keys be responsive. Tiny-dfr might need an (automated) restart via a script.

### Actual behavior

Device should properly resume, but the touchbar will stay black or show the default media keys, but the keys won't work.
