Passing a gfp_t to KUNIT_EXPECT_EQ() causes a cast warning: lib/kunit/string-stream-test.c:73:9: sparse: sparse: incorrect type in initializer (different base types) expected long long right_value got restricted gfp_t const __right Avoid this by testing stream->gfp for the expected value and passing the boolean result of this comparison to KUNIT_EXPECT_TRUE(), as was already done a few lines above in string_stream_managed_init_test().
