Subject: [PATCH] mailbox: ZynqMP IPI: Delete an error message in zynqmp_ipi_probe()
Date: Sun, 5 Apr 2020 15:16:01 +0200 [thread overview]
Message-ID: <28699a47-7770-7ce2-69fa-183a98c368b8@web.de> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 5 Apr 2020 15:10:16 +0200
The function “platform_get_irq” can log an error already.
Thus omit a redundant message for the exception handling in the
calling function.
This issue was detected by using the Coccinelle software.
