Subject: Re: [PATCH 0/5] PCI/pwrctl: Ensure that the pwrctl drivers are probed before PCI client drivers
Date: Mon, 4 Nov 2024 05:31:07 +0900 [thread overview]
Message-ID: <20241103203107.GA237624@rocinante> (raw)
In-Reply-To: <20241022-pci-pwrctl-rework-v1-0-94a7e90f58c5@linaro.org>
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
> the later one probes last). One such issue was reported for the Qcom X13s
> platform with WLAN module and fixed with 'commit a9aaf1ff88a8 ("power:

Applied to bwctrl, thank you!
