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.

Kind regards,
