Subject: broadcom-diag: reoder some parts.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=63d818a219ab1b93b3a9c1c22f59792924e76393;p=openwrt%2Fstaging%2Fthess.git

broadcom-diag: reoder some parts.

This was done to reduce the number of forward declaration needed.
This does not contain any real change in the code.
