It helps clean shutdown of PCIe. You can do this by adding a Fixes tag to your patch. In your case, it might be fixing whatever introduced the clk_bulk_prepare_enable, i.e.: Fixes: 0e898eb8df4e ("PCI: rockchip-dwc: Add Rockchip RK356X host controller driver") This would be put above your Signed-off-by in the first patch, after the empty line. To generate fixes tags like this, I use the following pretty format in my .git/config: [pretty] fixes = Fixes: %h (\"%s\") I can then do `git log --pretty=fixes` to show commits formatted the right way. To find which commit to pick, `git blame` and some sleuthing are helpful. With this tag, stable bots can pick the commit into any release that the commit it fixes is in.
