[PATCH 5.10 414/509] firmware: stratix10-svc: Fix a potential resource leak in svc_create_memory_pool()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

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.
