Subject: Re: [PATCH v3 0/5] PCI/pwrctrl: Rework pwrctrl driver integration
 and add driver for PCI slot

Hello,

> This series reworks the PCI pwrctrl integration (again) by moving the creation
> and removal of pwrctrl devices to pci_scan_device() and pci_destroy_dev() APIs.
> This is based on the suggestion provided by Lukas Wunner [1][2]. With this
> change, it is now possible to create pwrctrl devices for PCI bridges as well.
> This is required to control the power state of the PCI slots in a system. Since

Applied to pwrctrl, thank you!
