** Description changed: [ Impact ] Some HP ZBook Ultra Mobile Workstations have a sensor to wake up the system on human presence. This behavior is not always desirable (e.g. during suspend tests), and currently there’s no way to disable it. [ Fix ] - Cherry-pick the following patch series: + Cherry-pick the following patch series, which has been in the linux- + next: - [PATCH 0/3] Adjust behavior for HPD sensor[1] + [PATCH 0/3] Adjust behavior for HPD sensor[1] This introduce a new sysfs file (/sys/bus/pci/drivers/pcie_mp2_amd/*/hpd) to toggle the HPD sensor, and disable the HPD sensor by default.

If for some reason the camera needs this sensor in order to function normally, then this may cause regression in camera.
