> commit b921aa3f8dec ("PCI/pwrctrl: Switch to pwrctrl create, power
> on/off, destroy APIs") switched PCI pwrctrl users to explicit create and
> power control APIs, but only added the calls to the regular DesignWare
> host initialization path.

> Firmware-managed hosts bypass that path and probe the ECAM host bridge
> directly. Endpoints already powered by firmware, such as NVMe devices,
> remain discoverable. Endpoints that rely on Linux pwrctrl and pwrseq,
> such as WCN7850, remain powered off and cannot be discovered.
>
> Create and power on pwrctrl devices before probing the host bridge, and
> release them on errors.
