Public bug reported: [Impact] This test will require /dev/rtc0, the default RTC device, or one specified by user to run. Since this default RTC is not guaranteed to exist on all of the devices, so check its existence first, otherwise skip this test with the kselftest skip code 4.
Without this patch this test will fail like this on a s390x zVM: $ selftests: timers: rtcpie $ /dev/rtc0: No such file or directory not ok 1 selftests: timers: rtcpie # exit=22 We have this test disabled in our test suite with an if check [1], with this patch applied we can remove that code block.
