Presumably, this would be done only for files that use
__func__ as the first argument to printk.
Something like this might work moderately well.
$ git ls-files | grep '\.[ch]$' | \
xargs perl -i -e 'local $/; while (<>) {
s/\b(printk|pr_(?:emerg|crit|alert|err|notice|warn|warning|info))\s*\(\s*\"\%s(?:\s*\(\s*\)\s*)?(?:\s*:\s*)?\s*(?:\-\s*)?([^"]+)"\s*,(\s*)__func__\b/$1("%s:
$2",$3__func__/g; print; }'
