4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx>
commit 727f28b8ca24a581c7bd868326b8cea1058c720a upstream.
The interrupt is always allocated with devm_request_irq so it
must always be freed with devm_free_irq.
Fixes: 448e9c55c12d ("tpm_tis: verify interrupt during init")
