Maybe patch MAINTAINERS like the following could help keep you CC'd on all things PCI? But maybe that would be too much, never-the-less I'll make sure you are CC'd on pci related patches including cover-letters in the future. diff --git a/MAINTAINERS b/MAINTAINERS index f313862b2929..b64cd6bbb34f 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -15552,6 +15552,8 @@ F: include/linux/of_pci.h F: include/linux/pci* F: include/uapi/linux/pci* F: lib/pci* +K: pci +N: pci Palmer, we now have a branch you can use for your RISC-V for-next.
