Both patches are primarily to drivers/pci/controller/pci-hyperv.c, so
why do the subject lines look so different?
Instead of making up a new format from scratch, look at the previous
history and copy it:
$ git log --oneline drivers/pci/controller/pci-hyperv.c
f18312084300 ("PCI: hv: Remove unnecessary use of %hx")
41608b64b10b ("PCI: hv: Fix sleep while in non-sleep context when removing child devices from the bus")
88f94c7f8f40 ("PCI: hv: Turn on the host bridge probing on ARM64")
9e7f9178ab49 ("PCI: hv: Set up MSI domain at bridge probing time")
38c0d266dc80 ("PCI: hv: Set ->domain_nr of pci_host_bridge at probing time")
418cb6c8e051 ("PCI: hv: Generify PCI probing")
8f6a6b3c50ce ("PCI: hv: Support for create interrupt v3")
7d815f4afa87 ("PCI: hv: Add check for hyperv_initialized in init_hv_pci_drv()")
326dc2e1e59a ("PCI: hv: Remove bus device removal unused refcount/functions")
...
The second patch adds arm64 support, so it *should* mention arm64, but
it can be something like this:
PCI: hv: Add arm64 Hyper-V vPCI support
