Currently, there is no plan to address this in the kernel. During the patch review series, it was concluded to implement this in the Renesas way, which does not "pollute" the generic "xhci-pci.c", and requires the very same approach (initramfs building tools must address this issue to explicitly include `xhci-pci-prom21` same as `xhci-pci-renesas` (for dracut= ), or "correctly" detects the module tree for system-available devices in so called "dep" or "hostonly" mode (it seems dracut fails in this point but ot= hers look better in the handling routine). --=20 You may reply to this email to add a comment.
