platform_get_resource_byname() can return NULL, which would cause a crash

when passed the pointer to resource_size().

Move the fiu->memory_size assignment after the error check for

devm_ioremap_resource() to prevent the potential NULL pointer dereference.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version.
