Subject: Re: [PATCH 0/5] PCI/pwrctl: Ensure that the pwrctl drivers are
 probed before PCI client drivers

Hello,

> This series reworks the PCI/pwrctl integration to ensure that the pwrctl drivers
> are always probed before the PCI client drivers. This series addresses a race
> condition when both pwrctl and pwrctl/pwrseq drivers probe parallely (even when

Applied to bwctrl, thank you!
