Subject: [PATCH] ipmi_si: Avoid spurious errors for optional IRQs
Git-commit: 443d372d6a96cd94ad119e5c14bb4d63a536a7f6
Patch-mainline: v5.6-rc6
References: bsc#1161943
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().
