Can improved adjustments be provided as regular diff data
(without an extra attachment)?

* Please improve such a change description with imperative wordings.
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.10-rc6#n94

* How do you think about to use a summary phrase like
  “Use more common error handling code in brcm_pcie_probe()”?

Does this software update complete the exception handling?

Would you like to add any tags (like “Fixes” and “Cc”) accordingly?

I suggest to add a blank line before the second label.
