[PATCH v6 3/3] kunit: Use KUNIT_EXPECT_MEMEQ macro

From: Maíra Canal
Date: Tue Oct 18 2022 - 15:08:33 EST


Use KUNIT_EXPECT_MEMEQ to compare memory blocks in replacement of the
KUNIT_EXPECT_EQ macro. Therefor, the statement

KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0);

is replaced by:

KUNIT_EXPECT_MEMEQ(test, foo, bar, size);
