Subject: [PATCH] ipmi_si: Avoid spurious errors for optional IRQs
Date:   Wed,  5 Feb 2020 10:31:46 +0100
Message-Id: <20200205093146.1352-1-tiwai@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Although the IRQ assignment in ipmi_si driver is optional,
platform_get_irq() spews error messages unnecessarily:
  ipmi_si dmi-ipmi-si.0: IRQ index 0 not found

Fix this by switching to platform_get_irq_optional().

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
