All sample and test programs had a definition of mbedtls_param_failed. This was necessary because we wanted to be able to build them in a configuration with MBEDTLS_CHECK_PARAMS set but without a definition of MBEDTLS_PARAM_FAILED. Now that we activate the sample definition of MBEDTLS_PARAM_FAILED in config.h when testing with MBEDTLS_CHECK_PARAMS set, this boilerplate code is no longer needed.
