Description

In the Linux kernel, the following vulnerability has been resolved: firmware: stratix10-svc: Fix a potential resource leak in svc_create_memory_pool() svc_create_memory_pool() is only called from stratix10_svc_drv_probe(). Most of resources in the probe are managed, but not this memremap() call. There is also no memunmap() call in the file. So switch to devm_memremap() to avoid a resource leak.
