Subject: iommu/ipmmu-vmsa: Remove dev_err() on platform_get_irq() failure
Git-commit: 565d454280f85c0a4f204fb160f3d90f8418c080
Patch-mainline: v5.4-rc6
References: bsc#1175713
platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
This is detected by coccinelle.
