Subject: selftest: rtctest.c:290:alarm_wkalm_set:Expected -1 (-1) != rc (-1) :
 Test terminated by assertion

kselftest: rtc built with clang-16 getting failed but passed with gcc-12
build. Please find more details about test logs on clang-16 and gcc-12
and steps to reproduce locally on your machine by using tuxrun.

On the qemu-x86-64 clang builds it is intermittent failure;
you could notice that from the test history link below.
