Subject: [PATCH 3/9] lib: memcpy_kunit: Fix an invalid format specifier in an assertion msg
Date: Wed, 21 Feb 2024 17:27:16 +0800	[thread overview]
Message-ID: <20240221092728.1281499-4-davidgow@google.com> (raw)
In-Reply-To: <20240221092728.1281499-1-davidgow@google.com>

The 'i' passed as an assertion message is a size_t, so should use '%zu',
not '%d'.

This was found by annotating the _MSG() variants of KUnit's assertions
to let gcc validate the format strings.

Fixes: bb95ebbe89a7 ("lib: Introduce CONFIG_MEMCPY_KUNIT_TEST")
Signed-off-by: David Gow <davidgow@google.com>
