[PATCH] PCI: altera: Remove redundant platform_get_resource() return value check
From: Bjorn Helgaas
Date: Mon Aug 22 2016 - 15:26:04 EST
devm_ioremap_resource() fails gracefully when given a NULL resource
pointer, so we don't need to check separately for failure from
platform_get_resource_byname(). Remove the redundant check.
