Linux Kernel vulnerability analysis and mitigation

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

intel_th: fix device leak on output open()

Note that a recent commit fixed the leak in a couple of open() error paths but not all of them, and the reference is still leaking on successful open().
