Subject: [PATCH] rtc: Delete an error message in three functions
Date: Sun, 5 Apr 2020 17:36:15 +0200	[thread overview]
Message-ID: <04116352-b464-041c-1939-96440133aa6f@web.de> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 5 Apr 2020 17:30:15 +0200

The function “platform_get_irq” 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.
