Please fix the subject to be:

net: bcmgenet: Use fallthrough;

to match commits done to this file.

Joe, please use Subject line subsystem prefixes consistent with what would
be used for other changes to these drivers.

Thank you.

Not easy to do for scripted patches.
There's no mechanism that scriptable.

I'm not going to hand-edit 500 patches.

Then I'm not applying your stuff, it's as simple as that.

I have this to show me the top 3 prefixes used for files currently
modified in my tree:

tgs() {
    local fs

    fs=$(git status -s | sed -n 's/ M //p')

    git log --oneline --no-merges -- $fs | \
	sed -e's/[^ ]* \(.*\):[^:]*/\1/' | \
	sort | uniq -c | sort -rn | head -3
}

You could probably massage it to just give you to top one and feed 
that into git commit template?

I had already tried that via:

$ cat get_patch_subject_prefix.bash 
#!/bin/bash
git log --format="%s" --no-merges -200 --since=2-years-ago $@ | \
  cut -f1 -d":" | \
  sort  | uniq -c | sort -rn | head -1 | \
  sed 's/^[[:space:]]*[[:digit:]]*[[:space:]]*//'
$ 

It doesn't work very well for many of the subsystems.

For instance, this script produces things like:

ARM/ZYNQ ARCHITECTURE: treewide
FCOE SUBSYSTEM (libfc, libfcoe, fcoe): scsi
WOLFSON MICROELECTRONICS DRIVERS: ASoC

There isn't a great single mechanism for this.

At various times, I have proposed adding a grammar for
patch subject titles to MAINTAINERS.

Like:
