Subject: [PATCH 5.5 106/151] ipmi_si: Avoid spurious errors for optional IRQs

From: Takashi Iwai <tiwai@...e.de>

commit 443d372d6a96cd94ad119e5c14bb4d63a536a7f6 upstream.

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*()")
