Subject: selftests: harness: Mark functions without prototypes static
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d8b5290adb4f60c6a19f3c72bf24c6573a6f8cfb;p=users%2Fhch%2Fmisc.git

selftests: harness: Mark functions without prototypes static

With -Wmissing-prototypes the compiler will warn about non-static
functions which don't have a prototype defined.
As they are not used from a different compilation unit they don't need to
be defined globally.

Avoid the issue by marking the functions static.
