In the Linux kernel, the following vulnerability has been resolved:

reset: sunxi: fix memory region leak on ioremap failure

In sunxi_reset_init(), when ioremap() fails, the memory region obtained
via request_mem_region() is not released, leading to a resource leak.

Add an err_mem_region label to properly release the memory region before
freeing the data structure.
