From fc9a615200d48e076af58f4309f507e500ed900d Mon Sep 17 00:00:00 2001 From: David Gow Date: Wed, 28 Feb 2024 13:27:20 +0800 Subject: drm: tests: Fix invalid printf format specifiers in KUnit tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The drm_buddy_test's alloc_contiguous test used a u64 for the page size, which was then updated to be an 'unsigned long' to avoid 64-bit multiplication division helpers. However, the variable is logged by some KUNIT_ASSERT_EQ_MSG() using the '%d' or '%llu' format specifiers, the former of which is always wrong, and the latter is no longer correct now that ps is no longer a u64. Fix these to all use '%lu'. Also, drm_mm_test calls KUNIT_FAIL() with an empty string as the message. gcc and clang warns if a printf format string is empty, so give these some more detailed error messages, which should be more useful anyway.
