[drm:intel_power_well_disable [i915]] disabling PW_5
Some general information about the system I'm using:
- CPU: i3-11104G w/o discrete GPU
- System architecture:
x86_64
- Kernel version:
6.0.0-rc1+
- Linux distribution: Ubuntu 22.04
- Machine: Huawei MateBook E 2022
- Display connector: DSI-1
After my last issue was fixed and the driver is now loading, there are some new errors, which appear on every boot:
Sanity check warning from power management. The "backlight" here is a red herring, this is about the utility pin, which is used for TE signal on DSI command mode, not for backlight at all.

I'm not sure if I named this issue correctly, feel free to change the title to be more meaningful.
