CID 197605:  Null pointer dereferences  (FORWARD_NULL)
Dereferencing null pointer "param".

200 /* We need to cast these values since the toolchain doesn't
201 * provide inttypes.h

False positive. Confirmed by @mtpr-ot ("the ztest_test_fail() will abort the process if param == NULL, so no NULL pointer dereference is possible."). Flagged as false positive.
