It is inconsistent IS_ERR and PTR_ERR for rtc->rtcdev in rzn1_rtc_probe().

Generated by coccinelle script:

The proper pointer to be passed as argument is rtc->rtcdev.
Detected using Coccinelle.

Thanks for your patch. This has already been reported twice,
Alexandre will likely apply one of the fixes after the merge window.
