When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.

Fixes: 89576bebbc17 ("rtc: Use devm_platform_ioremap_resource()")
This doesn't fix an issue and it was anyway not introduced by that
commit. Please correct your commit message and subject.

OK, thanks for your reply.

I will remove the fixes tag and use the following patch subjects:
"rtc: goldfish: Use correct return value for goldfish_rtc_probe()"
"rtc: mpc5121: Use correct return value for mpc5121_rtc_probe()"

Thanks,
Tiezhu Yang
