[PATCH 2/4] [ARM] mvsdio: fix a memory leak

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

 



request_mem_region() will call kzalloc to allocate memory for struct resource.
release_resource() unregisters the resource but does not free the allocated
memory, thus use release_mem_region() instead to fix the memory leak.
