Re: [PATCH v5 0/2] ACPI: APEI: Add support to notify the vendor specific HW errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1) If you can post things as a series, i.e., with patch 1/2 and patch
2/2 being responses to the 0/2 cover letter, that makes things easier.
It looks like you did this for the previous postings.

2) When applying these, "git am" complained (but they did apply
cleanly):

  warning: Patch sent with format=flowed; space at the end of lines might be lost.
  Applying: APEI: Add support to notify the vendor specific HW errors
  warning: Patch sent with format=flowed; space at the end of lines might be lost.
  Applying: PCI: HIP: Add handling of HiSilicon HIP PCIe controller errors

3) drivers/pci/controller/pcie-hisi-error.c should be next to
drivers/pci/controller/dwc/pcie-hisi.c, shouldn't it?

4) Your subject lines don't match the convention.  "git log --oneline
drivers/acpi/apei" says:

  011077d8fbfe ("APEI: Add support to notify the vendor specific HW errors")
  cea79e7e2f24 ("apei/ghes: Do not delay GHES polling")
  933ca4e323de ("acpi: Use pr_warn instead of pr_warning")
  6abc7622271d ("ACPI / APEI: Release resources if gen_pool_add() fails")
  bb100b64763c ("ACPI / APEI: Get rid of NULL_UUID_LE constant")
  371b86897d01 ("ACPI / APEI: Remove needless __ghes_check_estatus() calls")

and "git log --oneline --follow drivers/pci/controller/dwc/pcie-hisi*"
says:

  6e0832fa432e ("PCI: Collect all native drivers under drivers/pci/controller/")
  8cfab3cf63cf ("PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplate")
  5a4751680189 ("PCI: hisi: Constify dw_pcie_host_ops structure")
  b379d385bbaa ("PCI: hisi: Remove unused variable driver")
  a5f40e8098fe ("PCI: Don't allow unbinding host controllers that aren't prepared")
  e313a447e735 ("PCI: hisi: Update PCI config space remap function")
  b9c1153f7a9c ("PCI: hisi: Fix DT binding (hisi-pcie-almost-ecam)")

So your subject lines should be:

  ACPI / APEI: ...
  PCI: hisi: ...
