Summary
platform/x86: thinkpad_acpi: Fix a memory leak of EFCH MMIO resource
Details

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

platform/x86: thinkpad_acpi: Fix a memory leak of EFCH MMIO resource

Unlike releasememregion(), a call to release_resource() does not free the resource, so it has to be freed explicitly to avoid a memory leak.
