From: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Subject: Documentation/kcov: Define `ip' in the example. 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.
