Subject: [PATCH] memory: fsl-corenet-cf: Fix handling of platform_get_irq() error
Git-commit: dd85345abca60a8916617e8d75c0f9ce334336dd
Patch-mainline: v5.10-rc1
References: git-fixes
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: 54afbec0d57f ("memory: Freescale CoreNet Coherency Fabric error reporting driver")
