From e316f1970d9c51ab167be0835a4cfbadf92e9653 Mon Sep 17 00:00:00 2001
From: Edward O'Callaghan <quasisec@google.com>
Date: Fri, 12 Aug 2022 13:28:46 +1000
Subject: tree: Change signature of extract_programmer_param_str()

Results can be reproduced with the following invocation;
```
 $ find -name '*.c' -exec sed -i 's/extract_programmer_param_str(/extract_programmer_param_str(NULL, /g' '{}' \;
```

This allows for a pointer to the actual programmer parameters
to be passed instead of a global.
