Subject: [PATCH v2 ] ipmi_si: Fix false error about IRQ registration
Message-Id: <95A6B0CD-9C09-4165-AF60-A2789C53E926@oracle.com>
To:     linux-kernel@vger.kernel.org
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message
to platform_get_irq()"), platform_get_irq() will call dev_err() on an
error,  even though the IRQ usage in the ipmi_si driver is optional.

Use the platform_get_irq_optional() call to avoid the message from
alerting users with false alarms.
