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.
