intel_th: fix device leak on output open()
Description
In the Linux kernel, the following vulnerability has been resolved: intel_th: fix device leak on output open() Make sure to drop the reference taken when looking up the th device during output device open() on errors and on close(). 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().
