Should anyone find this useful, I have these to check branches in my
local repos directly:

alias checkpatch='/path/to/checkpatch.pl -q --emacs --strict'

checkbranch()
{
    local commit
    local range

    if [ -z "$1" ]; then
	range="origin..HEAD"
    elif [ -n "`echo $1 | grep '\.\.'`" ]; then
	range="$1"
    else
	range="$1..HEAD"
    fi

    for commit in `git rev-list --reverse $range`; do
	git --no-pager log --oneline -1 $commit
	git format-patch --stdout -1 $commit | checkpatch -
    done
}

Then I can do:

Check local patches against origin:
$ checkbranch

Check local patches against drm-intel/drm-intel-nightly:
$ checkbranch drm-intel/drm-intel-nightly

Check a revision range:
$ checkbranch commit1..commit2

Do note that checkpatch is not the law. But it helps you get some of the
little things straight.


HTH,
Jani.
