[PATCH] rtc: Delete an error message in three functions

From: Markus Elfring
Date: Sun Apr 05 2020 - 11:36:50 EST

The function âplatform_get_irqâ can log an error already.
Thus omit redundant messages for the exception handling in the
calling functions.

This issue was detected by using the Coccinelle software.
