When using worktree, the src repo might already have a master branch,

clashes. dim_update_branches is also expecting the branch to be
called maintainer-tools.

I think the worktree stopped making sense, now that maintainer-tools
is a completely free-standing repo without a simple git clone would be
better. Plus maybe a git branch -m to rename the master branch to
maintainer-tools to keep dim_update_branches happy.

The worktree was really just to avoid having to constantly refetch
unrelated kernel commits for the maintainer-tools checkout, while that
was still living in drm-intel.

Would something like this work?

function simple_setup_aux_checkout # name url directory [branch]
{
        local name url dir remote branch

        name=$1
        url=$2
        dir=$3

        if [[ $# -eq 4 ]]; then
                branch=$4
        else
                branch=$name
        fi
        echo "Setting up $dir ..."

        if [ ! -d $dir ]; then
                git clone $url $dir
                remote=origin
        fi

        cd $dir
        if [ -z "$remote" ]; then
                remote=$(url_to_remote $url)
        fi

        if ! git_branch_exists $branch ; then
                if git_branch_exists $name; then
                        git branch -m $name $branch
                else
                        git checkout $branch -t $remote/$name
                fi
        fi
        cd - > /dev/null
}

Or should I just add something tailored for maintainer-tools?

Thanks,
Daniele
