commit 1995f15590ca222f91193ed11461862b450abfd6 upstream.
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.
