Subject: Documentation/kcov: Define `ip' in the example.
From: Sebastian Andrzej Siewior <[email-masked]>
Date: Mon, 30 Aug 2021 19:26:24 +0200

The example code uses the variable `ip' but never declares it.

Declare `ip' as a 64bit variable which is the same type as the array
from which it loads its value.
