Subject: [PATCH 5.19 113/192] kunit: fix assert_type for comparison macros

From: Sander Vanheule <sander@...nheule.net>

[ Upstream commit aded3cad909581c60335037112c4f86bbfe90f17 ]

When replacing KUNIT_BINARY_*_MSG_ASSERTION() macros with
KUNIT_BINARY_INT_ASSERTION(), the assert_type parameter was not always
correctly transferred.  Specifically, the following errors were
introduced:
  - KUNIT_EXPECT_LE_MSG() uses KUNIT_ASSERTION
  - KUNIT_ASSERT_LT_MSG() uses KUNIT_EXPECTATION
  - KUNIT_ASSERT_GT_MSG() uses KUNIT_EXPECTATION

A failing KUNIT_EXPECT_LE_MSG() test thus prevents further tests from
running, while failing KUNIT_ASSERT_{LT,GT}_MSG() tests do not prevent
further tests from running.  This is contrary to the documentation,
which states that failing KUNIT_EXPECT_* macros allow further tests to
run, while failing KUNIT_ASSERT_* macros should prevent this.

Revert the KUNIT_{ASSERTION,EXPECTATION} switches to fix the behaviour
for the affected macros.

Fixes: 40f39777ce4f ("kunit: decrease macro layering for integer asserts")
